Abstract :
Microstrip patch antenna with circular corner truncation is proposed to achieve polarization reconfigurability. By applying forward bias, reverse bias or zero bias to the four PIN diodes, the antenna can radiate with right hand circular polarization (RHCP), left hand circular polarization (LHCP) and linear polarization (LP). Simulations as well as experimental results show that proposed antenna demonstrates a very good impedance match for all the three different polarizations without any additional matching network.
