Abstract

This manuscript presented the development of a circularly polarized (CP) antenna array that implemented square ring slot in the center of the patch and the power weighting distribution method for its feeding line. This array antenna consists of 7 circular patches and is slotted by a square ring slot. Resonant frequency of the antenna design set at 9.4 GHz and its bandwidth 0.8 GHz. A power weighting distribution feeding line is implemented. This method is intended to suppress the sidelobe level of the antenna. Meanwhile, to enhance the CP properties, a square ring slot is inserted over each center of the patch. Then, to accomplish the axial ratio under 3 dB, the patch is truncated by a pair of square shapes at the 45° and -45°. The proposed antenna array has circular polarization with sidelobe level (SLL) around -15.1 dB at the frequency of 9.4 GHz. Its reflection coefficient, S11 bandwidth up to 1 GHz, then lower than -20 dB. 3 dB axial ratio obtained 0.9 GHz.
