Quad Band Microstrip Antenna for Mobile and GNSS Application

Abstract

In various applications, multiband are desirable. This Paper presents the design of a Quad microstrip patch antenna. For this project is use of quad frequency for GSM and IRNSS band. In this system GSM and IRNSS band combine and use at a one platform. The substrate material FR4 is selected for microstrip patch antenna design. An analysis of the return loss, gain of the proposed antenna is carried out using ADS (Advanced Design System) software. The result shows that the return loss of 22.81 dB is achieved at first resonant frequency of 850-900MHz, 19.54 dB at second resonant frequency of 1.84 GHz, 21.08 dB at third resonant frequency of 1.13 GHz, 20.66 dB at forth resonant frequency of 2.5 GHz.
