Design and realization of microstrip antenna for GPS application using proximity coupled techniques

Wireless technology development has driven many innovations in the realization of the antenna. Microstrip antenna is one of the very popular antenna which has been used on the navigation system such as Global Positioning System (GPS). In this research has been designed a microstrip antenna in form of rectangular array that is supplied with proximity coupled method using FR-4 Epoxy. This antenna is designed by reorienting the rectangular array by 45°. This designed antenna is implemented at frequency 1575.42 MHz. The measurement shows that the designed antenna has gain = 6.21 dB, return loss (S11) = −13,91 dB, Voltage Standing Wave Ratio (VSWR) = 1.5, bandwidth = 41 MHz and able to generate dual polarization.
