Ka-band planar slotted waveguide array based on groove gap

Ka-band planar slotted waveguide array based on groove gap slot array antenna Abstract A circularly polarized radial line slot array with enhanced bandwidth is presented in this letter The proposed antenna consists of slot pirates A circularly polarized element on a rectangular waveguide has generally small reflection It consists of orthogonal two slot antennas excited by 90-degree phase

slot pirates The antenna is designed to work at 110 GHz with strong directivity Based on the principle of a waveguide–slot antenna, the initial dimensions

slot machine gif Abstract A center-fed slot array antenna based on ridge gap waveguide technology is presented In the proposed structure, no aperture blockage is TL;DR: In this paper, a dual-layer partially reflective surface was placed above a slot antenna operating at 60 GHz and fed by a printed ridge-gap
