This paper presents a compact dual-feed patch antenna capable of achieving dual-polarized radiation suitable for applications demanding frequency reuse or polarization diversity. Circular polarization is obtained by feeding the antenna with 90° phase shift between its two ports using Wilkinson power divider having λ/4 difference between its outputs. This proposed circularly polarized antenna is suitable for GPS applications.
