Abstract
The study of microstrip patch antennas has made great progress in recent years. Compared with conventional antennas, microstrip patch antennas have more advantages and better prospects. Different researchers have used different dielectric substrates to fabricate microstrip patch antenna. So a question arises that which dielectric substrate among the common substrates available gives better performance and what are the properties of the dielectric substrates which affects antenna performance. So a comparative study has been performed to know the dielectric properties of five different substrates which affect antenna performance. The aim is to design and fabricate five triangular microstrip patch antennas on five different substrates and analyze their radiation characteristics. The antenna is designed to work for X-band applications. The resonant frequency is taken 10 GHz and height of the dielectric substrate is kept constant i. e. , 1. 5mm for all the five antennas. The antenna is showing good results on 8 GHz frequency. This shift in the frequency is due to the fringing fields along the edges. This study will help for authors and researchers to get a fair idea of which substrate should be given preference and why to fabricate microstrip patch antenna.
