摘要：
In this article, a simple design of a stacked patch dual band circular polarized antenna is designed and tested that can be used for GPS L1 (1575.42 MHz) and L2 (1227.6 MHz) applications. The lower patch is designed for L2 band, and the upper patch is designed for L1 band. Circular polarization in the upper patch is achieved by inculcation of corner truncation, and in lower patch it is achieved by inclusion of both corner truncation and an I-slot. A peak gain of 5.5 and 4.5 dBic is achieved at L1 and L2 bands with a broad beam required for GPS applications. It exhibits a minimal axial ratio of 0.6 dB. The fabricated prototype is experimented. In addition, a parametric analysis was performed to study the impact of antenna performance due to various geometrical parameters.
