In this article, a multi elliptical structured antenna is designed in which
its ground plane is etched with different radius of elliptical SRR. The antenna size is
44×40×1.6mm3, the substrate used is FR-4 substrate which is having a dielectric
constant of 4.4. The proposed antenna approach is determined using four iterations
achieve the maximum radiation performance. The antenna is working under 1.96GHz
-3.74GHz, 3.95GHz – 7.48GHz, 8.42GHz – 11.47GHz and 13.41GHz –
18.93GHz bands, the antenna can work for the WLAN, Wi-Fi & Wi-MAX applications.
The design and analysis of the proposed radiating structure is carried out using ANSYS
EM desktop and met material unitcell setup validation is carried out is an added
advantage to the proposed antenna
Index Terms: CPW, met material loading, elliptical split ring, and unit cell.
