摘要
In this article, a novel microstrip patch antenna is presented, with both frequency and polarization reconfigurabilities. By controlling the states of the switches loading on the patch, the antenna can operate in two distinct frequency bands (the frequency ratio is 1.16) and, at the upper band, it can provide two reversed circular polarizations (CP). Simulation and measured results validate the design. The frequency and polarization diversities of this design could potentially improve the functionality and reliability of wireless communication systems.
