A Wideband Zeroth-Order Resonance Antenna for Wireless Body Area Network Applications

초록

A wideband on-body antenna for a wireless body area network for an Industrial, Scientific, and Medical band is proposed. A wideband characteristic is achieved by combining two zeroth-order resonance (ZOR) modes at adjacent frequencies by controlling the value of the shunt capacitance. The size of the proposed antenna is 0.072 lambda(0) x 0.33 lambda(0), and the measured 10-dB return loss bandwidth is 340 MHz (14.3%). In addition, the resonance frequencies operating in the ZOR mode are insensitive to the effects of the human body by virtue of the ZOR characteristic.
