A wideband circularly polarized slot spiral antenna array excited by a printed gap waveguide (PGW) feeding network is presented in this paper. The equiangular slot spiral is etched on the top wall of the substrate integrated cavity (SIC) in which TE120 mode is excited. Due to excitation of this mode. electric field distribution in two halves of the substrate integrated cavity is the s... https://www.jmannino.com/hot-choice-Lions-Big-Chain-Necklace-mega-pick/
