AN EXPERIMENTAL STUDY ON OPTIMIZATION & METHODS OF MICROSTRIP PATCH ANTENNA

Physics

The design of a microstrip patch (MP) antenna using the Moth-Flame Optimization (MFO) algorithm for UWB applications is presented in this article. MP antennas are designed to operate in dual- and multi-band applications as it has the following advantages such as low cost, light weight and easy installation. In order to reduce the microstrip patch cross-polarized radiation and achieve the required radiation parameters, the MP antenna is designed with a faulty ground structure. The substrate of liquid crystal polymer is used here to reduce the material cost and the applied geometry parameters are used to improve the antenna performance. The MFO Optimized Antenna 50mm ×50mm represents the compact size, which improves the performance of the antenna. However, the simulation process is performed by MATLAB tools with a high frequency structure simulator for parameter optimization and performance analysis respectively. The antenna has an operational bandwidth of 3.1 GHz and a return loss of -20 dB which covers UWB (3.1–10.6 GHz) applications. The simulation results demonstrate good impedance bandwidth, radiation pattern, directivity and relatively constant gain over the entire band of frequency compared to earlier methods. In conclusion, the proposed system may be a better choice for the design of microstrip antennae in communication system to cover Bluetooth operation, Wi-Fi, Wi-Max, telemedicine and UWB applications.
