A simple configuration using a crossed-slot feed with a single microstrip line or a triplate line without such a coupler to obtain the required phase shift is proposed. Measurement results on this circularly polarized microstrip antenna are presented. By using the crossed-slot feed method, a microstrip antenna with an axial ratio of less than 2 dB in a wide angle range was obtained. From these results, it was verified that circular polarization operation can be obtained by the proposed method.
