Description
Summary:This paper presents a compact asymmetric CPW fed monopole antenna using Denim fabric as substrate applicable for UWB communication and various wireless body area networks (WBANs). The geometry of the antenna consists of a circular monopole antenna with a modified ground plane and introduction of defected ground structures (DGS) to achieve ultra‐wide band (3.10–10.6 GHz) characteristics. The proposed wearable antenna operates from 2.40 to 14.88 GHz providing a fractional bandwidth (FBW) of about 144.44%. Enhancement of the bandwidth is obtained by the insertion of open ended rectangular slit in the ground plane. The final antenna produces a peak gain of about 6.57 dBi at 13.05 GHz and achieved omnidirectional radiation patterns. In terms of return loss, gain, and radiation characteristics, the lightweight flexible wearable antenna is fabricated, and the tested effects are found to be in fair accordance with the simulated ones. Key Points Compact asymmetric CPW fed monopole antenna using denim fabric as substrate applicable for UWB communication The final antenna produces a peak gain of about 6.57 dBi and achieved omnidirectional radiation patterns On‐body measurements and deformation through bending is performed to provide validation to the structure
