Design, Simulation and Fabrication of Patch array antenna for Indian Regional Navigation Satellite System

Abstract

The modern mobile communication systems requires high gain, large bandwidth and minimal size antenna’s
that are capable of providing better performance over a wide range of frequency spectrum.This paper presents the
design of microstrip rectangular patch antenna with center frequency at 1.176GHz for IRNSS application. The array of
four by one (1x4) patch array microstrip rectangular antenna with microstrip line feeding based on quarter wave
impedance matching technique was designed and simulated using Advance design system(ADS) tool. The performance of
the designed antenna was than compared with the single patch rectangle antenna in term of return loss, Voltage
Standing Wave Ratio (VSWR), bandwidth, directivity, radiation pattern and gain. The array antenna on the substrate
type FR-4 with dielectric constant of 4.6 and thickness of 1.6mm respectively
