Abstract

This paper presents two configurations of fourelement polarization-agile patch antenna array: corner-to-corner and side-to-side arrangement of simple stub-loaded elements. By feeding sequentially with 0.4λ element spacing at 1.575 GHz for GNSS applications on 1.6-mm FR4 substrate, both structures are smaller than the common half-wavelength spacing arrays, and have very low axial ratio of sub-0.1 dB, coupling coefficients of less than-22 dB, and realized gain of 5.68 dBic for RHCP and 6.18 dBic for LHCP of corner-to-corner configuration, as well as a CP gain of 6.81 dBic for side-to-side configuration to explore the effects of coupling on array performance.
