摘要

A dual-band circularly polarized antenna with AR (Axial Ratio) bandwidth enhanced using parasitic strips and triangle notches is proposed in this paper. The proposed antenna comes with a size of 53×53×3.813 mm (0.64λg×0.64λg×0.046λg at 2.45 GHz), which is composed of two layers of substrate and three layers of metallic patterns. With the introduction of parasitic strips on the top metallic layer and etched triangles on the ground plane, this antenna exhibits dual-band circularly polarized character. A flexible frequency ratio from 1.57 to 2.01 could be obtained by changing the size of the triangle notches. Simulations and measurements verified that the proposed antenna shows relative S11<-10 dB bandwidth of 36.6% (2.23–3.25 GHz) and 51.3% (3.58–6.05 GHz), relative AR<3 dB bandwidth of 17.6% (2.32–2.77 GHz) and 11.1% (4.65–5.30 GHz), peak gains of 4.45 dBic and 6.24 dBic, respectively. This antenna is a good candidate for the 2.45 GHz communication band and the 5G sub-6 NR band applications.
