Dual‐Port Ceramic Array Antenna Integrated With Polarization Converter for 5G mm‐Wave Networks

ABSTRACT A two‐port dielectric antenna for mm‐wave frequency range has been constructed and examined in this study. The alumina ceramic resonator is excited by the structure via aperture coupling. The design's originality is emphasized by three salient features: (a) Circularly polarized waves may be produced in the working range of 31.8–32.45 GHz using polarization convertor suspension; (b) 1 × 2 array formation improves measured gain close to 9.5 dBi; and (c) antiparallel placement of antenna terminals/SNG MS suspension reduces the coupling level to below −35 dB. An effective working range of 31.45–33.25 GHz is confirmed by experimental validation. Broadsided radiation is guaranteed by the excitation of the basic hybrid HEM 11δ mode. Due to stable radiation feature and diversity parameters, the suggested antenna is applicable for the lower portion of the mm‐wave spectrum and future FR2 extensions.
