## Abstract In this article, one wideband circularly polarized microstrip antenna array has been proposed and investigated. The technique of sequential rotation subarray has been employed to construct the whole antenna array, which enhances the impedance bandwidth and axial ratio (AR) bandwidth by
## Abstract The circular polarization characteristics of stacked microstrip antennas with a single coaxial feed are analyzed by the method of moments. Green's functions for the patch currents are formulated in the spectral domain. Galerkin's method is employed to determine the input impedance, farβ

## Abstract By adopting a sequential rotation technique with the use of an Lβstrip microstrip line to feed the proposed patch antenna array, a broadband design for circular polarization (CP) is proposed and experimentally studied. The impedance bandwidth and 3βdB axialβratio bandwidth of the circul
