Compact textile UWB antenna with hexagonal for biomedical communication

Abstract

This paper introduces a small-sized, low profile, planar and flexible ultra-wide band (UWB) antenna using Jeans, a textile material as the substrate. A novel shape of hexagonal slot in rectangular step shape patch with partial ground plane is developed with bandwidth of 12 GHz is proposed. It is the primary approach in using natural textile as the substrate for UWB antenna which operated in a wide range of bandwidth. The UWB antenna is designed for short range applications including wireless body area network (WBAN), which is the current revolution with growing demands in wireless sensor networks. The antenna operates from 2.8 to 10.9 GHz, which is a suitable candidate for WBAN operation.
