Abstract

A circular-ring patch on-body antenna with a shorting via for WBAN application is proposed. The proposed circular-ring patch antenna has the maximum radiation direction along the body surface for on-body communication in the industrial, scientific, and medical (ISM) 2.45 GHz band. In order to achieve low profile, the proposed antenna used shorting vias to excite TM₃₁ mode at ISM 2.45 GHz. To enhance bandwidth performance, an annular ring with shorting via is closely located around a circular patch. Proposed antenna is fed by a via connected with a microstrip line. The overall dimension of proposed antenna is 60 mm × 65 mm × 3.15 mm.
