Microstrip Inverted F Antenna for GPS Application

Abstract

A design of compact micro strip inverted F antenna for GPS application is presented. Proposed model is an Inverted-F antenna which receives all the operating frequencies of GPS receiver ranging from 1.176 GHz to 1.575 GHz placed in automobiles. The antenna structure is fabricated, to maintain the axial ratio of 2dB to 3dB and also to achieve circular polarization. FR4- Fiber Glass (Epoxy) is used as Substrate with a Dielectric Constant of 4.4. Copper is used as Radiating Element. The parameters such as Frequency, Return loss, VSWR, Impedance, Radiation pattern and Directivity of the proposed model is simulated by HFSS (High Frequency Structure Simulator) software of Version 13.
