Abstract

A new reconfigurable single-feed circular microstrip antenna with polarization diversity is proposed. The simple structure of this antenna contains a radiating circular patch, four switches (PIN diode), and a 50 Ω microstrip feed line. It can be switched between four different states: two states for linear polarization (LP), one state for left hand circular polarization (LHCP) and one for right hand circular polarization (RHCP). Simulation and experimental results show that the proposed antenna demonstrates a good impedance bandwidth, and axial ratio in the circularly polarized states.
