Abstract
In this paper, Antenna is an evergreen field of research because of its never-ending demand in the modern communication era. In this paper metamaterial antenna is presented. “Meta” a Greek word defines “beyond” the materials provide properties beyond conventional materials. In this paper the metamaterial and micro patch antenna concepts are combined to improve the performance of the ordinary patch antenna. This metamaterial antenna is designed in FR4 Epoxy substrate with dielectric permittivity of 4.4, height of the substrate is 1.6 mm and loss tangent tan δ = 0.02 with a simple shape of rectangular patch of dimension 40 mm length and 30 mm width. This antenna is simulated in an integral based solver simulation software called CST Microwave studio v2018 and yielded best results such as return loss − 46.58 dB, VSWR 1.009 and bandwidth of 574 MHz, directivity is 3.379 dBi, gain is 3.23 dBi for the resonant frequency(fr) of 2.4 GHz. The feeding network is also designed for better integration in real time applications. This antenna is further fabricated and tested for the validation and obtained, VSWR 1.3, Return loss − 26 dB and Bandwidth of 200 MHz. This metamaterial antenna is suitable for 2.4 GHz WiFi applications.
