The antenna features a high efficiency dual-band WiFi 2.4 GHz/56 GHz right hand circular polarization (RHCP). The antennas improve upon the previously developed antennas by simplifying the construction and simplifying the feed, while retaining circular polarization across two widely-separated bands. In...

By embedding shorting vias, a dual-feed and dual-band L-probe patch antenna, with flexible frequency ratio and relatively small lateral size, is proposed. Dual resonant frequency bands are produced by two radiating patches located in different layers, with the lower patch supported by shorting via...
Microstrip patch antennas represent one family of compact antennas that offer a conformal nature and the capability of ready integration with communication system's printed circuitry. In this paper, a 5.4 GHz circular polarization microstrip antenna is designed and simulated. The selected microstrip anten...
a wideband patch antenna is proposed. by using the dual-layer patch configuration and modified l-strip feed technique, the impedance bandwidth of the patch antenna for vswr<1.2 is broadened to 22% with respect to 900 mhz, which is superior to the other available patch antennas. in addition,...
