This paper describes the design of a 3-bit circularly-polarized transmitarray antenna operating in Ka-band. The array is based on a unit-cell composed of two U-shaped slot loaded patch antennas, which are connected by a metallized via hole and printed on two identical dielectric substrates. The latter are separated by a ground plane and bonded by a CuClad 6700 film. A 400-element transmitarray is...
E-shape patch antenna is proposed for millimeter wave frequencies. Using this E-shape structure, the patch antenna is designed for wideband operation at about 31.6-40 GHz for millimeter wave communication. Simulated and measured results for main parameters such as return loss, impedance bandwidth, radiation patterns and gains are also discussed herein. The study shows that modeling of such antennas,...
