Abstract
A triple band circularly polarized square microstrip antenna is proposed. The antenna has two pair of crank slits at each edge and is excited by an L-probe feed. With simulations, the operational principle for circular polarization at triple band are clarified. The simulated bandwidths of 2-VSWR with 3dB-axial ratio are approximately 10MHz at triple band in GPS(L1/L2/L5 bands).
