Abstract: We design a center-feed post-wall waveguide slot subarray of 25 radiating elements that suppresses E-plane sidelobes below -18 dB for the 76.5 GHz band (76.0 GHz to 77.0 GHz). First, by ...
Abstract: The concept of the frequency diverse reconfigurable intelligent surface (FD-RIS) technology has been introduced, which can enable simultaneous implementation of distance-angle beamforming in ...
