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...
In this letter, a reconfigurable rhombus-shaped patch antenna with a Y-shaped feedline for polarization diversity is proposed. This antenna exhibits a simple structure, which consists of a rhombus-shaped patch, two p-i-n diodes, and a Y-shaped feedline. The two p-i-n diodes are inserted in the gap between the rhombus-shaped patch and the Y-shaped feedline. In order to easily supply a dc bias voltage...
