In this paper, a textile based fractal monopole antenna is proposed with a defected ground structure for wearable application. The proposed antenna is designed on Flannel fabric with a thickness of 1 mm, which translates to 0.03λ at 10 GHz. The total dimensions of proposed antenna is 60 x 40 x 1 mm. The measured fractional bandwidth of the antenna is 110.1%. The proposed flannel based conductive ink antenna is characterized, and the results for washable fabric are illustrated. Both simulated and measured results are presented. The concept of application of low cost conductive ink on flannel fabric is demonstrated using conventional screen printing method. The antenna is characterized for commercial wash ability; the measurement results are invariant with the machine wash of the flannel fabric indicating robustness of the proposed method of fabrication of the antenna element.
