Description:TECHNICAL FIELD
[0001] The present disclosure relates generally to field of wireless communication. More particularly, the present disclosure provides a superwideband multiband antenna for applications including Bluetooth/LTE2600.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Wireless technologies plays important role in modern era where one can find existing wireless communication system for numerous applications. Ultra wideband (UWB) technology working in bandwidth range of 3.10GHz-10.6GHz given by Federal Communication Commission (FCC) in 2002 opened wide gates for when development of wireless system for applications including imaging systems, wall imaging systems, through wall imaging systems, surveillance systems, medical systems etc. Also, higher frequency side bandwidth is considered, say X and Ku band, applications involving Radar and satellite communication systems are also part. To design such a wireless communication system, a larger bandwidth antenna is required and hence ratio bandwidth=10:1 has to be maintained which solves above requirement of bandwidth and hence leads to super wideband bandwidth. However, existing wireless communication system including WiMAX (3.30GHz-3.80GHz), WLAN (5.150GHz-5.825GHz) and Downlink Satellite System (DSS: 7.25GHz-7.75GHz) are also working in ultra wide band (UWB) bandwidth range and needs to be eliminated by using filters.
[0004] Existing antennas for eliminating interfering bands can include fractal antenna with quasi-self complimentary characteristics intended for UWB applications encounters above interference by etching U-shape slot in ground & feed line and X-band interference is encountered by using split ring resonator (SRR). On other hand, metamaterial property can be used to obtain dual band operation of antenna working for 2.40GHz and 5.80GHz. Decagonal shaped geometry with slotted ground plane intended for UWB applications and tapering of both radiating & transmission line with single resonator realizes WiMAX and WLAN bands. A single iterated patch antenna with dual etched slots provides dual notch functional antenna. UWB antenna including circular patch and rectangular ground plane containing L-shaped stub with etched slots/notches and a parasitic element near patch is useful for detection of cancer at early stage. Loading of Split Ring Resonator between two arms of patch antenna results in diversity applications and a quasi self complimentary fractal utilizing both slot and stub using mushroom shaped slotted electromagnetic band (EBG) near feed line introduces triple notch with pentagonal patch.
[0005] Also, a circular patch with EBG structure notches WiMAX and WLAN interfering band and major challenges encountered in designing above antennas are investigated. A leaf shaped radiating patch with two etched rectangular slot and circular SRR pair above ground also removes interfering bands. A superformula based monopole antenna with rejection of dual interfering band and fractal antenna converted from basic circular patch also eliminates three interfering bands. A folded dipole reported can work for applications such as GPS, DCS, WLAN and WiMAX wireless system. By using either circular or hexagonal split ring resonators, notched bands are controlled and a dual band antenna designed for S and X band radar applications is reported. Modified ground plane including to bevels and radiating patch etched with circular slot with rectangular CSRR placed near feed line provides triple notched band characteristics. A antenna designed intended to work in lower GSM (900MHz) and UWB band with band notch characteristics, dual polarized wide beamwidth antenna for application between two access points were radiating elements are placed orthogonally and also, four step patch and three step ground including two slits generates multi notches by using split ring slot, double strip slots and L-shaped slots is designed for triple notch function.
[0006] Also, a compact antenna with triple notch characteristics consisting of elliptical patch also provides prevention of working triple interfering bands. Low profile structure of radiating elliptical patch is obtained by using artificial magnetic conductor ground plane and broadband operation for bandwidth 6GHz to 13GHz is recorded for broadband circularly polarized Fabry-Perot resonator. Also, a four notched band antenna using pair of L-shaped slots, complimentary co-directional SRR and a pair of C-shaped stubs. Bandwidth enhancement is also obtained by using tapered micro strip feed and using L-shaped slot, notched band is obtained. Hybrid reflector improves gain at lower frequencies while high gain is maintained at higher frequency band. Broader bandwidth and high gain is achieved by using stacked topology for Radar applications.
[0007] There is a need to overcome above mentioned problems of prior art by bringing a solution that facilitates rejecting interfering bands with help of the one or more fractal stubs and one or more slots. Also, the solution can facilitate offering good radiation pattern, maximum gain, maximum radiation efficiency and good time domain analysis and shows good performance with regardless to time domain analysis (Group delay and Impulse response).

[0049] In an embodiment, the WLAN interfering band and the DSS interfering bands can be eliminated by etching pair of bent C-shaped slot on the radiating patch (104). By varying one or more parameters, bandwidth of the notched bands either shifts towards lower or higher frequency side.

The maximum surface current density distribution within the one or more stubs and around one or more slots infers that there can exist high mismatch impedance condition and that one or more input signals received by the radiating patch (104) can be reflected back to input port leading to notched band characteristics.
[0051] In an illustrative embodiment, the transceiver (100) can be include a transmitter, and a receiver, where correlation between transmitted (TX) and received (RX) signal can be established by calculating fidelity factor which can be given by Equation 1

In another illustrative embodiment, for minimum distortion less transmission of one or more input signals, good linearity of phase of the transmitted one or more input signals can be maintained. Phase response of transfer function can be evaluated by a group delay which can be defined as rate of change of total phase shift with respect to angular frequency and can be given by Equation 2

[0052] In an illustrative embodiment, the transceiver (100) can have a constant group delay in entire operating band, and where the transceiver (100) can facilitate finding applications not only in ultra wide band (UWB)/X/Ku band, but also in lower band applications like Bluetooth LTE2600, and the likes. In another illustrative embodiment, gain of the transceiver (100) without notched bands can vary between 3.69-4.94dBi. In another illustrative embodiment, gain measurement of the transceiver (100) can be carried out by with help of the transmitter and the receiver. Friis transmission equations can be used to calculate unknown gain of the transceiver (100) which is given below
(1)
(2)
where PT and PR can be transmitted power and received power. GT and GR can be gain of the transmitter and the receiver, where the transmitter and the receiver can be identical (GT=GR=GP) and ‘d’ can be distance between the transmitter and the receiver. can be corresponding wavelength for respective frequency for which gain is to be calculated. For notched band transceiver (100), gain falls to 6.95dBi at 3.59GHz, 8.95dBi at 5.58GHz and 7.98dBi at 7.56GHz respectively. For remaining operating band, the transceiver (100) can be configured to maintain the gain of 3.39dBi-4.98dBi.
[0053] In an illustrative embodiment, radiation efficiency for the transceiver (100) can be 28% at 3.55GHz, 21% at 5.63GHz & 21% at 7.32GHz and for remaining band, the radiation efficiency range can be maintained between 79%-89%. In another illustrative embodiment, measured radiation patterns including co-polarization and cross-polarization in H-plane (x–z plane) and E-plane (y–z plane), where Omni directional radiation pattern with low cross-polarization level can be observed on x–z plane. The radiation patterns on the y–z plane can be like a small electric dipole leading to bidirectional patterns in a very wide frequency band. Radiation pattern at higher frequencies can deteriorate due to change in area of radiation and current distribution which is non uniform over radiating surface of the transceiver (100) which can be cause for beam splitting in cross polarization. As a result, both radiation patterns in H and E planes show high cross polarization and more distortion for the transceiver (100).
[0054] In an illustrative embodiment, the transceiver (100) can be a compact monopole antenna with 3.5/5.5/7.5GHz triple notched band characteristics. In another illustrative embodiment, the transceiver (100) can be super wideband antenna for Bluetooth, LTE2600, UWB, X and Ku band applications, where the super wideband antenna can be configured to cover large useable bandwidth of frequency range 2.34-20.0GHz, but not limited to the likes with at least three interfering bands.

In another embodiment, the transceiver (100) can include a substrate (102), a radiating patch (104), one or more fractal stubs (106), one or more slots (108), a connector (110) and a ground (112). In an illustrative embodiment, a radiating patch configured with the substrate, wherein the radiating patch is configured to receive a first set of electromagnetic bands; and one or more fractal stubs configured with the radiating patch, wherein the one or more fractal stubs are adapted to eliminate a second set of electromagnetic bands from the first set of electromagnetic bands. In another illustrative embodiment, the first set of electromagnetic bands can be selected from a group of electromagnetic bands including S, Ku, Ka, X, Worldwide interoperability for microwave access (WiMAX), wireless local area network (WLAN), downlink satellite system (DSS), and the likes. In yet another illustrative embodiment, the second set of electromagnetic bands can include at least three interfering bands, where the at least three interfering bands can include WiMAX, WLAN and DSS, but not limited to the likes.
[0067] In an illustrative embodiment, the radiating patch (104) can include a at least two identical ellipses, where the at least two identical ellipses can be inclined at the pre-determined angle, where the pre-determined angle can be twice angle made between tangent and semi major axis of the at least two identical ellipses 2?3. The at least two identical ellipses can include a first ellipse with semi major axis as R1 and semi minor axis as R2, and a second ellipse with semi major axis R3 and semi minor axis R4, where R1=R3 and R2=R4. In another illustrative embodiment, the inclination of the at least two identical ellipses can facilitate wide operating bandwidth of the pre-determined frequency range, where the predetermined frequency range can include two point two seven gega hertz (2.27 GHz) to eighteen point eight five gega hertz (18.85 GHz), but not limited to the likes.
[0068] In an embodiment, the WLAN interfering band and the DSS interfering bands can be eliminated by etching pair of bent C-shaped slot on the radiating patch (104). By varying one or more parameters, bandwidth of the notched bands either shifts towards lower or higher frequency side. In an illustrative embodiment, as value of L2 is changed from 2.70mm to 3.30mm, bandwidth of WiMAX interfering band can also shifts from 3.35GHz-3.92GHz to 3.62GHz-4.31GHz, but not limited to the likes. For L2=2.70mm, intended WiMAX notched band is achieved. In another illustrative embodiment, when L3 is changed from 3.00mm to 4.00mm, bandwidth can also change from 3.63GHz-4.28GHz to 2.96GHz-3.65GHz and for L3=3.50mm, bandwidth can corresponds to 3.36GHz-3.91GHz. In yet another illustrative embodiment, the one or more parametric change corresponding to the WLAN interfering band for parameter L5, where the change in L5 from 4.00mm to 5.00mm can encounter bandwidth change from 4.94GHz-6.15GHz to 4.69Gz-5.53GHz, but not limited to the likes.
[0069] In an illustrative embodiment, the one or more parametric change for L6 corresponding to the DSS interfering notched band and change in L6 from 4.25mm to 3.75mm can facilitate changing bandwidth from 7.91GHz-8.85GHz to 7.36GHz-8.15GHz, but not limited to the likes. In another illustrative embodiment, during optimization of the notched band parameters, operating bandwidth can be preserved. In yet another illustrative embodiment, filter action of triple notched band for WiMAX interfering band, WLAN interfering band, and DSS interfering band can be studied by simulating surface current density distribution at centre notched band frequencies. The surface current density distribution for frequency range 3.58GHz shows that maximum current can be concentrated within the one or more fractal stubs intended to notch WiMAX interfering band, where surface current density distribution for centre frequencies 5.41GHz and 7.53GHz respectively can correspond to WLAN interfering notched band and DSS interfering notched band, where the maximum surface current density distribution can be observed around bent C-shaped stubs.
