摘要

A broadband, circularly polarized (CP), new structure, dipole-shaped antenna is proposed in this article. The antenna is composed of dipole-shaped patch, FR4 substrate, ground and feeding coaxial cable. A double-printed semicircular ring is utilized to feed the radiator. An optimized antenna with an oversize of 0.42λ₀ × 0.42λ₀ × 0.136λ₀ 0.75 × 0.75λ₀ × 0.15λ₀ (at 1.32 GHz) is designed and measured. The measured results show that the proposed antenna yields an impedance bandwidth (IBW) of 36.8%(1.24–1.8 GHz), a 3-dB axial-ratio (AR) bandwidth of 24%(1.32–1.68 GHz), and an average gain of 9.1 dBic in the operating frequency band.
