Abstract :
A novel microstrip antenna with four L-slits for achieving circular polarization (CP) operation is proposed. By introducing two pairs of the centrosymmetric L-slits, the high cross-polar level is effectively suppressed. The characteristics of the input impedance, axial ratio, and radiation patterns are simulated. The results show that the good CP performance of the proposed antenna can be obtained.
