Abstract :
Several single feed truncated corner circularly polarized microstrip antennas with different substrate thickness are studied. It is found that the axial ratio bandwidth could be enhanced considerably when a thicker substrate is used, provided that a U-slot and/or L-probe are used to tune the impedance matching. One of the configurations attains an axial ratio bandwidth (Lt3dB) of about 14% within the impedance matching band when the substrate thickness is about 0.2lambdao.
