This paper describes the design of an ultra - wideband (UWB) antenna which works above the frequency of 1GHz and resonates at 4GHz for wearable applications. Initially, to achieve the wideband antenna design, the parameters related to the microstrip patch antenna have been used. Further, to achieve the wideband range of frequency the ground plane of this antenna is designed as a semi - rectangular plane. To improve the antenna parameters mainly return loss, gain, directivity, the metamaterial structures are designed on the above of the microstrip patch antenna which is usually placed at a distance of 22.5mm. Then for wearable application, the antenna has to be very flexible and lightweight, therefore, the substrate for designing antenna and metamaterial structure, the polyester material has been used whose dielectric constant is 3.2 and height is 1.6mm. Then the research concentrates on the comparison study between three different shapes of MTM unit cell array. MTM structures are based on Artificial Magnetic structures which are commonly known as Split Ring Resonators (SRR). The proposed antenna design with metamaterial is analyzed and simulated by Ansoft HFSS software.
