Design a Microstrip Patch Antenna for Multi-Service Purposes

This paper presents the design, simulation and optimization of different microstrip patch antenna for multiservice purposes. Here we have designed four different types of antennas––E-shaped patch antenna using the substrate Rogers RT/Duroid whose resonating frequency is 2.5 GHz and bandwidth is 500 MHz. Secondly, we have designed a U-shaped patch antenna using the substrate RT/Duroid (2.2) whose resonating frequency is 2.4 GHz and bandwidth is 150 MHz. These two types of antenna are single band antennas and we have an octagonal–rectangular patch antenna using the substrate FR4_epoxy(4.4) which operates at two resonating frequency 8.5 GHz and 15.5 GHz and bandwidth is 550 MHz and 650 MHz, respectively. A dual-band U-shaped patch antenna is designed in succession of single-band U-shaped antenna Then we have compared the parameters like bandwidth, return loss and resonating frequency of 4 types of antenna to find out the best among all and their different applications.
