Extended UWB wearable logo textile antenna for body area network applications

In this paper, a novel extended Ultra Wide Band (UWB) wearable logo-type textile antenna for body area network applications is presented. The substrate of the proposed antenna is made of Fleece fabric with permittivity 1.17. The proposed antenna comprises of a hexagonal radiating patch and a partial ground plane. Ultra wide bandwidth is attained by optimizing the geometry, introducing a square notch in the partial ground plane and introducing novel slot pattern on the radiating patch of the antenna. This novel slot represents the logo of author's department name “Electrical and Electronic Engineering (EEE)”. The dimension of the proposed antenna is 38 × 32 × 2.05 mm

and the bandwidth is 27 GHz starting from 2.85 GHz to 29.85 GHz for return loss less than -10 dB. The gain variation is less than 4.5 dBi and average total efficiency more than 93%. The proposed antenna design details and simulated results are presented by the Commercial electromagnetic simulation package CST Microwave Studio.
