"Dual Frequency Antenna Aperture"
Abstract: The invention provides an antenna structure comprising at least two stacked antenna apertures, a first antenna aperture with first antenna elements and at least a second antenna aperture with second antenna elements. The antenna structure is arranged for operation in at least a high and a low frequency band. The first antenna elements are arranged for operation in the high frequency band and said second antenna elements for operation in the low frequency band. The first antenna elements are arranged to have a polarization substantially perpendicular to the polarization of the second antenna elements. The second antenna elements are arranged in at least one group and each of said group, comprises a number of second antenna elements coupled in series and arranged to have a common feeding point on a straight feeding structure. One feeding structure is located adjacent to each group of second antenna elements. The direction of the feeding structure is substantially perpendicular to the polarization of the first antenna elements. The invention also provides a corresponding method and a radar system comprising the antenna structure.
