A D-Band Center-Feed Linear Slot Array Antenna Based on Gap Waveguide
Paper i proceeding, 2019
In this paper, the design of a linear slot array antenna based on gap waveguide for D-band applications is investigated. The antenna includes 16 slots and the feeding element is completely based on the ridge gap waveguide. The simulated results on return loss and radiation pattern are presented and discussed. The simulated results show a gain more than 19 dBi and a return loss less than 10 dB over 10% relative bandwidth from 134 to 148 GHz.
