Comparison of Six Different Dielectric Substrates in Microstrip Patch Antenna Design

Microstrip patch antenna (MSPA) is the most popular antenna type due to the small size, easy to fabricate, simple and inexpensive construction, lightweight and low volume, conformity with planar and non-planar surfaces, dual and triple frequency operation in recent years. Especially, due to the becoming the size of the devices becoming smaller, desire to design MSPA has gained more importance than before. In this study, as a result of comparison between six different types of antennas, showed us which of the substrate or substrates give us the best performance of the newly designed patch antenna could be chosen. Based on this, in this study, designed rectangular MSPA simulated with six different substrates which are FR4 Glass Epoxy with 4.3, ROGERS DT5880 with 2.2, ROGERS 4003C with 3.3, Teflon with 2.1, Arlon AD300A with 3 and last Alumina with 9.9 dielectric constant. The study includes a copper patch antenna and copper ground working at 5.8 GHz. The six substrates are kept constant at 1.6 mm height. Good results gained at the desired frequency of 5.8 GHz antenna which is at the resonant frequency between 5.7-5.9 GHz. The main aim of this study is to support their research and create an idea about the six different substrates which can be prepared by researchers while choosing the substrate of the MSPAs.
