Abstract

A dual-band dual-mode patch antenna for on-on-off wireless body area network (WBAN) applications is proposed. The antenna consists of a half-circular patch with two shorting posts to generate a TM₄₁ higher-order resonant mode and a bottom ground slot to generate additional resonance. To reduce the antenna size without seriously affecting the radiation pattern, the antenna is cut in half and operates in half-mode. The antenna has a vertical monopole-like radiation pattern in the 2.45 GHz industrial, scientific and medical (ISM) band and a horizontal monopole-like radiation pattern in the 5.8 GHz ISM band. To evaluate the body effect, both 2.45 and 5.8 GHz muscle-equivalent phantoms were used. The overall dimensions of the proposed antenna is 30.5 × 62 × 3.15 mm.
