A simple single feed circularly polarized microstrip antenna with Koch curve as boundary is presented. The two pairs of rectangular microstrip antenna edges are replaced by a Koch curve of 1st stage and 2nd stage with different indentation angles to get circular polarization. The proposed method is simple and easy to obtain circular polarization with reasonable 3 dB axial ratio bandwidth and 10 dB impedance bandwidth. The dependency of aspect ratio and fractal dimension of the boundary on the performance of the circularly polarized antenna is discussed.
