Abstract :
A reconfigurable patch antenna with symmetrical structure for polarization diversity is proposed in this article. The proposed antenna mainly consists of a rhombus-shaped patch with single feed, two conductive pads with via hole and two PIN diodes. The antenna can produce right-hand circular polarization (RHCP) and left-hand circular polarization (LHCP) by adjusting bias state of two PIN diodes. The fabricated antenna satisfies a 10-dB bandwidth of 100 MHz in the RHCP and LHCP as well as it has -3dB axial ratio bandwidth of 55 MHz.
