Antenna’s Profile Miniaturization and Performance Booster Using Metamaterial

EasyChair Preprint no. 8597

Abstract

Antennas are an integral part of any wireless communication systems and also demanded to be compact in size as it is easy in its fabrication while having a good performance. Some of the antenna have its capability in maintaining the performance but still bulky in size which is not fulfil the current requirements in wireless communication system. Hence, in this project, low profile miniaturization and the performance booster of an antenna using metamaterial is proposed that operates at 2.4 GHz for Wi-Fi application. The proposed antenna is designed with a modified microstrip patch antenna with FR-4 substrate of 1.6 mm thickness having size of 37.02 mm × 26.00 mm from the rectangular microstrip patch antenna. After that, the antenna is integrated with the metamaterial of artificial magnetic conductor (AMC) which having the size of 49.89 mm× 49.89 mm. Then, the performance of the antenna is analysed and evaluated in terms of area of patch antenna, reflection coefficient, frequency bandwidth and directivity in comparison with and without integration of metamaterial. The antenna is designed and simulated by using Electromagnetic (EM) wave simulator software and further improved to ensure the antenna can operate at 2.4 GHz with implementation of metamaterial. Throughout the simulation, it is found that the area of patch antenna has decreased by 62.12% from 1085.26 mm² to 411.25 mm². Also, the proposed antenna offers high reflection coefficient by 46.38% from -17.29 dB to -25.31 dB whereas frequency bandwidth increased from 28 MHz to 69 MHz by 146.43% of increment. The directivity is improved by 19.48% whereas other performance such as impedance matching, gain and efficiency is reduced by 5.91%, 35.24% and 45.89% respectively. Therefore, the proposed antenna is suitable for Wi-Fi applications at 2.4 GHz.
