A V-Band Low Sidelobe Cavity-Backed Slot Array Antenna Based on Gap Waveguide
Paper in proceeding, 2020
A cavity-backed slot antenna array element is designed to operate in V-band with low sidelobe level (SLL). The 2 - 4 element array is fed by a groove gap waveguide (GGW) cavity in the bottom layer. Simulated results indicate that the array element can achieve a 7.4% bandwidth (59.7-64.3 GHz) with a gain of more than 16.5 dBi. Besides, the low SLL characteristic is achieved and the simulated first SLLs are below -20 dB across the desired working band.
