Abstract :
A novel CPW-Fed reconfigurable circular polarization microstrip antenna is presented. Two PIN diodes are attached to achieve polarization diversity. By switching the diodes ON or OFF, the proposed antenna can be operated either RHCP (Right Hand Circular Polarization) mode or LHCP (Left Hand Circular Polarization) mode. The experimental result shows that the proposed antenna has a circular polarization bandwidth (AR ≤ 3dB) of about 415MHz at the center frequency of 2.4GHz for both RHCP and LHCP mode. Measured results show good agreement with simulated ones.
