A novel compact textile antenna with the appearance of a button on clothing for body-centric wireless communications systems (BWCS) is presented. The antenna is placed on a textile substrate and fed by a coaxial line through the ground plane. The operating bandwidth of the antenna has met the requirement of the UWB communication system. The effects of the human body on S11 and S21 are presented and discussed in detail. The proposed antenna has good omni-directional radiation patterns and stable H-plane radiation patterns. The measured results show that the antenna is suitable for BWCS.
