Abstract

A textile antenna designed for Wireless Body Area Network (WBAN) is presented. The antenna is based on a capacitive loaded metallic circular ring that exhibits multimode characteristic at 2.4 GHz. The multimode behaviour is obtained using four feeding ports excited with specific phase configurations. The proposed antenna can be easily integrated into clothing due to its thickness and flexibility. Furthermore, its multimode behaviour helps to reduce the attenuation originated by NLOS (Non Line of Sight) environments and multipath propagation. The performance of the multimode antenna is similar to a MIMO system, but using a single antenna, so the space necessary in human body is minimized. For this reason, the multimode antenna constitutes a compact solution for WBAN applications.
