CPW-FED TEXTILE ANTENNA FOR WEARABLE WIRELESS COMMUNICATION APPLICATIONS

Abstract

Textile-based miniaturized antennas (20×26×1mm³)are designed and analyzed for wearableC-band applications. The proposed antenna uses two rectangular slots to form the first aid-structured antenna. The antenna uses copper foil as a conductive for ground and radiator layers and denim as a dielectric substrate. The structure is simple, compact, conformal, and easy to manufacture using only fabric material. Usually, a primary rectangular antenna has a narrow bandwidth. This paper proposes a rectangular and circular textile-based first-aid structured antenna for wearable applications with enhanced bandwidth. The two antennas resonate at 6.5GHz, 7.3GHz frequencies with reflection coefficients of -28.9dB and -36.4dB. The gains are observed at 4.37dBi, 5.07dBi, and obtained bi-directional radiation patterns. Bending analysis is also performed to prove sustainability under deformation.
