Abstract
This paper presents the impact of dielectric substrates with different relative permittivity used in designing a square ring patch antenna. Choice of suitable substrate material is essential while configuring the square ring microstrip patch antenna, since dielectric constant of a substrate is a basic parameter over regulating return loss, gain, bandwidth, voltage standing wave ratio (VSWR), and effectiveness of radiation pattern. Two fundamental properties of substrate material is considered in this research i.e. dietetic constant and loss tangent. Therefore, increasing the permittivity of substrate material permits compact size of antenna, but return loss, gain and directivity of antenna diminishing with admiration to the increment of dielectric substrate. The proposed geometric antennas have been designed utilising Computer Simulated Technology (CST) Microwave and MATLAB as a tool for the application, the antenna is acknowledged utilising a square ring patch simulated with different dielectric constant and contains radiating patch and ground plane. It has been considered several of dielectric material whose permittivity ranges from 1.96 to 6.15 relying on demand of GSM at desired frequency 1.8 GHz.
