Abstract
The proposed work illustrates the small circular wearable antenna for ultra-wide band (UWB) application. The designed work consists of a circular top patch of 15 mm radius and two square slots of dimensions 6 mm2 at center and 10 mm2 at the top of patch are created. The partial ground plane concept is used to get a wide bandwidth with a dimension of 27 mm × 50 mm. To describe the wearable applications, the light weight jean material is used as a non-conducting dielectric material with the εr of 1.7 and the substrate height of 1 mm. The designed antenna is resonating at the frequency range of 2.27 GHz to 15.18 GHz for ultra-wide band (UWB) applications. Also the bending performance of the proposed antenna is investigated at the radius of 80 mm and the angle of 0˚. The simulated and measured results of S11 parameter of the proposed antenna are below −10 dB for 2–16 GHz UWB frequency range. The group delay of antenna also is calculated and simulated values of group delay vary from 0.0473 ns to 0.4502 ns and measured 0.1217–0.9852 ns for the wide frequency band. The different antenna parameters are analyzed for this frequency band and the designed antenna is validated on VNA of 20 GHz.
