摘要：
A higher order mode (TM31) circular-ring patch on-body antenna with shorting pins for on-body communications in wireless body area network is proposed. Using shorting pins, TM31 resonance mode was generated, while achieving compact low-profile structure with monopole-like radiation characteristics. To obtain wide bandwidth, an annular ring with shorting pins having TM31 mode is closely located around the circular patch. The antenna has the overall dimensions of 0.49 lambda(0) x 0.53 lambda(0) x 0.025 lambda(0) at 2.45 GHz in the industrial, scientific, and medical 2.45 GHz band (2.4-2.485 GHz) and the 10-dB return loss bandwidth is 7.3% ranging from 2.35 to 2.53 GHz.
