Abstract: The FRC fractal antenna is analyzed using the MOM (method of moment), and verified with Designer, and a good agreement is obtained between their results. The FRC fractal is smaller than the theoretical size of the original rectangular patch with the similar VSWR (voltage standing wave ratio) and pattern. A 32-element microstrip array antenna is designed, with high gain, low sidelobe and fan beam with Taylor distribution, pointing at 47° from the normal. The experimental results of the fabricated antenna reach a bandwidth of 5°, the SLL of-20 dB and the cross polarization level of-20 dB, which verifies the result of the MOM.
