Abstract
ABSTRACT The design and analysis of a compact textile antenna, exhibiting wideband operation from 2.59 to 6.67 GHz and from 10.18 to 12.98 GHz, supporting multiple communication services in S, C, X and Ku bands, is presented in this paper. The multiband and wideband operations are comprehended in a single antenna structure by introducing Triple Notch Circular Patch Antenna (TNCPA) with a Defected Ground Structure (DGS). The reduced return loss, safe electromagnetic radiation and high gain are realized using the presented geometry. The prototype of TNCPA with the Quarter Ground Structure (QGS) functioning as DGS is fabricated using a wearable cotton substrate of dimension 28 × 28 mm2 and the measured results linger close to the simulated results with stable radiation performance.
