A Novel Wideband Circularly Polarized Patch Array with Meta-Surface
By
Progress In Electromagnetics Research Letters, Vol. 62, 1-8, 2016
Abstract
A wideband sequential-phase-feeding circularly polarized (CP) patch array is proposed in this paper. A well-designed meta-surface is placed above the array to enhance its impedance and axial ratio (AR) bandwidths. The proposed patch array has an overall size of 1.275λo×1.275λo×0.0935λo at 5.1 GHz. Measured results show that the impedance bandwidth (|S11|<-10 dB) of the array is 24.26% from 4.74 GHz to 6.05 GHz, and its 3 dB axial ratio bandwidth is 19% from 4.75 GHz to 5.75 GHz. The measured gain of the array at 5.7 GHz is 10.8 dBic. The measured results agree well with the simulated ones.
