A Polarization Diversity Patch Antenna with a Reconfigurable Feeding Network
This paper proposes a reconfigurable square patch antenna with polarization diversity. The proposed antenna consists of a square radiating patch and a Y shaped feed structure with two PIN diodes. The shape of the feed structure can be changed by adjusting the bias states of the two PIN diodes, which helps switch between two orthogonal linear polarizations. The polarization diversity characteristic is validated by the simulated current distribution and the measured radiation pattern.
