Abstract

In this work, we presented microstrip antenna operating at 1.575GHz frequency of (GPS applications). Microstrip patch antennas are widely used in Global Positioning System (GPS) applications due to their compact size, low profile, and ease of integration with RF circuits. This manuscript presents the design, simulation, and performance analysis of a rectangular microstrip patch antenna operating at the GPS L1 frequency (1.575 GHz). The antenna is designed on an FR-4 substrate with a dielectric constant (εᵣ) of 4.4 and a thickness of 1.6 mm. Key performance parameters such as return loss, voltage standing wave ratio (VSWR), radiation pattern, and gain are evaluated using electromagnetic simulation software (ANSYS HFSS/CST Microwave Studio). While the antenna simulation was done using advanced design system (ADS-Agilent) software. The proposed antenna demonstrates good impedance matching, directional radiation characteristics, and a gain of approximately 3–5 dBi, making it suitable for GPS applications.
