Abstract:
A new reconfigurable microstrip patch antenna allowing switching between two circular polarizations is proposed. It consists of a square radiating patch and a 3 dB hybrid coupler. Using only a single-polar-double-throw (SPDT) switch,the polarization switching can be achieved. This design of the dc-bias network is extremely simple. From experimental results,the proposed antenna avoids the frequency offset phenomena which often happened to antennas with switchable polarization.
