Dual-band on-body antenna for in-on-on WBAN repeater applications

Abstract

A dual-band on-body antenna for in-on-on wireless body area network repeater applications is proposed. This antenna consists of a dual-patch antenna and a zeroth-order resonance (ZOR) element. The two patch antenna elements form dual resonances that cover the 2.4 GHz ISM band. In addition, a triangle cut made at the lower edge of patch Element 1 improves the impedance matching in the 2.4 GHz ISM band. The ZOR element operates in the 403 MHz MICS band. The antenna has near surface radiation in the 2.4 GHz ISM band and nearly omnidirectional radiation in the 403 MHz MICS band. To evaluate the performance of the antenna on a human body, the proposed antenna is placed on a human equivalent flat phantom. (c) 2016 Wiley Periodicals, Inc.
