A wideband slot array antenna at W-band with a single-layer corporate feeding network is presented in this letter. The radiating slots are fed by open-ended rectangular waveguides to widen the impedance bandwidth instead of commonly used coupling mechanism. subarray two elements placed H-plane designed. In order fit into one layer, compact hybrid used, which combination ridge and E-plane hollow...

Radiative hyperthermia is a clinically applied cancer treatment modality where antenna design crucial to achieving therapeutic goals. Serving as the building block of phased-array configuration, antennas are typically arranged in cylindrical or elliptical array called applicator. This short communication proposes an phased applicator based on compact, UWB from category double-ridged horn custom...
