A novel single-feed wide band planar circularly polarized (CP) slot antenna is presented. This slot antenna consists of an L-shaped feeding stub with metamaterial inspired complementary split ring resonator (MICSRR) and a wide 45° rotated square aperture. Broadband impedance and CP radiation bandwidth (BW) is achieved by using a novel artificial exciting stub with defecting CSRRs on it. By controlling...
This paper presents wideband compact differential reflective phase shifters based on the double layer slot-coupled coupler configuration. These novel phase shifters arrangement consists of a 3-dB hybrid coupler with the coupled and transmission ports terminated with elliptically shaped microstrip loads. By altering the ports termination of the coupler, phase shifters propose differential phase ranging...
This paper describes a new Wilkinson power divider on a single-layer microstrip line that can reduce the occupied area, suppress the harmonic components, and/or provide the arbitrary power division ratios. It consists of two-section transmission lines, two inductors, and one isolation resistor. Four different designs have been conducted to investigate the capabilities of the structure. In addition,...
