Abstract

A novel low-profile GNSS microstrip circular polarization antenna is proposed and analyzed. Circular polarization is realized by asymmetric structure patch, and arc structure loaded on the main radiator can keep two modes orthogonal over a wide-angle range, so that the antenna has an extremely wide 3 dB axial ratio beamwidth (ARBW). The far-field AR beamwidths obtained are 232° and 212° respectively in the main plane of φ=0° and φ=90°. In φ=45° and φ=135°, 3 dB AR beamwidths are 241° and 244°, far exceeding the 120° required for satellite applications. In the whole CP band, 78.95% of the beam width exceeds 180°. The profile is only 0.0156λ₀, which is suitable, especially, for portable wireless systems or devices. The return loss bandwidth of -10 dB is 5.13% (1.52 GHz-1.6 GHz), which covers BeiDou Navigation System B1 (1.561 GHz). The axial ratio bandwidth is 1.28% (1.55 GHz-1.57 GHz), and the in-band peak gain is 4.09 dBi.
