Abstract:
A wide-beam circularly polarized (CP) asymmetric-microstrip antenna with four unequal circular-patches is proposed for global navigation satellite systems. Four unequal circular-patches are integrated symmetrically onto corners of a square microstrip radiator for CP radiation with wide-beamwidth. The measured 3-dB axial ratio (AR) bandwidth of the proposed antenna is 24.0 MHz (1.568–1.592 GHz) with a 3-dB AR beamwidth of around 180◦ across the bandwidth and a 10-dB return loss bandwidth is 56.0 MHz (1.556–1.612 GHz) with a gain of more than 5.0 dBic. The overall size of the antenna is 0.373λo×0.373λo×0.016λo at 1.6 GHz.
