A Design of Elliptical Edge-Fed Circularly Polarized Patch Antenna for GPS and Iridium Applications

This study presents a design of an elliptical edge-fed circularly polarized patch antenna to facilitate GPS and Iridium dual-band satellite applications like Search and Rescue (SAR) operations. The simulation of the antenna was performed in CST simulation software in the frequency range of 1.3 GHz - 2 GHz. The proposed antenna provides good matching with low $S_{11}$ in the dual-band: GPS (1.563 GHz - 1.587 GHz) and Iridium (1.616 GHz - 1.6265 GHz). Additionally, the simulated realized gain and axial ratio are in compliance with the required specifications. This design provides a cost-efficient and compact solution for the required dual-band application.
