Abstract
A new and circularly polarized (CP) antenna is proposed for global navigation satellite systems (GNSS) applications. The antenna employs a single feed and two orthogonally elliptical printed dipoles. The dipoles are crossed through a 90° phase delay line of a vacant-quarter printed ring to achieve CP radiation. In order to achieve broad beamwidth, four metallic cylinders are introduced. The proposed antenna has achieved a bandwidth of about 43% from 1.08 to 1.69 GHz for S11 < -10 dB. Meanwhile, the CP bandwidth is from 1.55 to 1.63 GHz (L1) and 1.12 to 1.26 GHz (L2, L5) for axial ratio < 3 dB. Additionally, the antenna yields right-hand circular polarization (RHCP) and high antenna efficiency over a wide frequency band. The simulated results have shown that the proposed antenna is a good candidate for GNSS applications.
