Progress In Electromagnetics Research Letters, Vol. 43, 105-113, 2013
Abstract
A high-gain and low-cost circularly polarized antenna array is proposed, which consists of four sequentially rotated circularly polarized square slot antennas (CPSSA). A novel feeding network is applied to the four-element array antenna, which results in increasing the axial ratio (AR) bandwidth. The measured impedance bandwidth for VSWR<2 is around 3.48 GHz (3.75 GHz~7.23 GHz) exhibiting a 2.8 GHz (3.8 GHz~6.6 GHz) 3 dB axial-ratio bandwidth (ARBW) and 9.05 dBic peak gain. The simulated and measured results are in good agreement with each other to verify the design.
