Design and development of printed dipole antenna with array configuration for GPS application

A compact, high gain printed dipole antenna is proposed for GPS application. As modern wireless devices have become more portable and cost effective, they have become an integral part of the day to day life of civilized society. A single element printed dipole antenna at 1.575GHz is designed and developed using FR4_Epoxy substrate. Its subsequent development into two elements and four elements array antenna is designed with increased gain suitable for GPS application. The antenna is simulated using Empire 3D FDTD based simulation tool. The antenna is fabricated and tested to confirm the simulated results. The return loss and gain of single element, two elements and four elements array antenna are −22dB, −22.57dB, −23.82dB and 2dB, 4.59 dB, 8.01 dB respectively.
