Designing and Analysis of Microstrip Patch Antenna for Wi-Fi Communication System Using Different Dielectric Materials

Abstract

Wireless communications has become very popular now-a-days. Wireless communication and networking system has become an important area for research in academic and industrial institutes. Wires provide less free space and non-mobility, thus indoor wireless communication system takes interest. Microstrip patch antennas has low weight and low profile, conformability, easy and cheap fabrication costing, that’s why it has been widely used in a various useful applications now a days. Microstrip patch antenna is designed for Wi-Fi communication which operates using 2.4 GHz frequency band. This research paper represents the effort of designing and performance analysis of microstrip patch antenna for Wi-Fi communication system. The main objective of this paper is to design and observe the performance of the designed microstrip patch antenna using different dielectric materials. Better performance is observed for FR4. For FR4 the return loss, S11isobtained - 11.4 dB at 2.4 GHz, this indicates the return loss is much lower comparing to the other dielectric materials used in this research. Also VSWR is found 1.74 which is desirable. In this paper we also observed and analyzed the radiation pattern of far field region, gain, radiation efficiency and total efficiency for different dielectric materials.
