Open full text 5 citations

Abstract

Antennas are one of the most significant component of RF microwave communication system. Microstrip patch antennas are widely used for this purpose. Having compact size with good characteristics are the prime advantage of microstrip patch antenna. Limitation with this patch antenna is also significant in terms of bandwidth. This paper presents different feeding analysis for patch antenna such as inset feed, transmission line feed, coaxial feed and aperture coupled feed.A microstrip patch antenna is designed and simulated at 2.4 GHz with the help of ANSYS HFSS simulation software. For the proposed antenna inset feed and coaxial feed are used .Return loss of -23.01 dB,-19.6 dB and antenna gain of 7.67dB, 7.69 dB are observed for inset feed and coaxial feed respectively.
