Compact and Wearable Microstrip-based Textile Antenna with Full Ground Plane Designed for WBAN-UWB 802.15.6 Application

摘要

The design and evaluation of a microstrip-based textile antenna for the IEEE 802.15.6 Wireless Body Area Network Ultrawideband (WBAN-UWB) application is presented in this paper. This textile antenna is designed with an innovative and compact UWB radiator on top of the overall structure with a full ground plane on its reverse side. The radiator based on a microstrip patch combined with multiple miniaturization methods resulted in a simple topology and a compact size of 39 mm x 42 mm x 3.34 mm to facilitate fabrication using simple tools. Meanwhile, the full ground plane enables the antenna operation in the vicinity of the human body with minimal body coupling and radiation towards it, ensuring operational safety. Besides the mandatory WBAN-UWB low and high band channels, the designed antenna also operated in five other high band channels, exhibiting a total bandwidth of 3.4 GHz.
