The article discusses the design and analysis of microstrip patch antennas for GPS applications. It focuses on achieving high gain and circular polarization (CP) with compact and efficient designs. The study includes a single patch antenna with a diagonal slot, a 2 × 1 patch array, and a 4 × 1 patch array. Key performance metrics like return loss, axial ratio, and gain are analyzed. The findings reveal that arrays provide higher gain and directivity, making them suitable for enhanced GPS performance. The 4 × 1 array shows a maximum gain of 11 dB and satisfactory CP operation, making it the most efficient design.

The article discusses the design and analysis of microstrip patch antennas for GPS applications. It focuses on achieving high gain and circular polarization (CP) with compact and efficient designs. The study includes a single patch antenna with a diagonal slot, a 2 × 1 patch array, and a 4 × 1 patch array. Key performance metrics like return loss, axial ratio, and gain are analyzed. The findings reveal that arrays provide higher gain and directivity, making them suitable for enhanced GPS performance. The 4 × 1 array shows a maximum gain of 11 dB and satisfactory CP operation, making it the most efficient design.
