Design and Implementation of Printed Folded Dipole Antenna for GPS Application

Antennas play a vital role in the design of any communication system. The printed antennas play a vital role since they have a variety of beneficial properties like mechanical durability, compactness, cost effective manufacturing. A compact high gain antenna for GPS applications is developed in this paper. This involves design and development of a folded dipole antenna with their array configurations at 1.575 GHz. The processes involve the design of a single element folded dipole on FR4_Epoxy substrate and its subsequent development into two element and five element array antenna. The antenna is simulated using Empire 3D FDTD based simulation tool. The antenna is then fabricated using this optimized design and tested to confirm the simulated results. The return loss of the single element, two element and five element folded dipole antenna are -31.3dB, -28.63dB and -20.04dB respectively.
