Keywords:
Metamaterial, Micro Patch Antenna, WLAN, Radar, Wireless Communication.Abstract
Antenna design plays major role in wireless product development. In this paper novel metamaterial structure is added in the circular patch antenna for operating in multiband frequency applications. “Meta” is a Greek word which means “beyond" the materials provides properties beyond the conventional materials. A circular patch antenna is provided with the novel metamaterial structure in its ground plane which is used to improve the performance of the regular patch antenna. In this research FR4 substrate with dielectric permittivity of 4.4 and height of the substrate is 1.6 mm is used for developing the metamaterial antenna. The Proposed antenna having compact dimension such as 24 mm length and 24 mm width. This metamaterial antenna is designed with an integral based solver simulation software called CST Microwave studio v2018 and obtained VSWR <1.5, Return loss of -15 to -30 dB and Bandwidth of 120-220 MHz, gain of 4.5-6.4 dBi at the resonant frequencies of 5.3 GHz, 7 GHz and 7.7 GHz. This metamaterial antenna is suitable for C band WLAN and X band radar applications
