Dual-Band Slot Array Antenna for W-Band Application Based on Gap Waveguide
A co-aperture dual-band linearly polarized slot array utilizing ridge gap waveguide (RGW) technology has been developed to operate within the 74 – 78 GHz and 102 – 106 GHz frequency ranges. The subarray features two sets of longitudinal slots positioned on the broad wall of the single waveguide channel, allowing for dual-band radiation through a planar aperture. Furthermore, two bandpass filters (BPFs) are placed on either side of the subarray, enabling independent feeding and filtering characteristics for the dual bands. A subarray column of several slot elements has been designed and simulated to demonstrate the dual-band concept. The subarray can produce high-gain beams when expanded into a planar array configuration.
