A simple single-layer dual-band dual-mode metasurface antenna for on/off-body wireless body area network (WBAN) communication is proposed. By properly adjusting the size and arrangement of the surrounding patches, the on-body omnidirectional mode is significantly enhanced. The antenna can excite off-body broadside pattern mode by introducing an arc-shaped slot at its center. The results show that the proposed antenna achieves a broadside radiation at lower frequency of 2.4 GHz band and an omnidirectional pattern at higher frequency of 5.8 GHz band.

摘要

A simple single-layer dual-band dual-mode metasurface antenna for on/off-body wireless body area network (WBAN) communication is proposed. By properly adjusting the size and arrangement of the surrounding patches, the on-body omnidirectional mode is significantly enhanced. The antenna can excite off-body broadside pattern mode by introducing an arc-shaped slot at its center. The results show that the proposed antenna achieves a broadside radiation at lower frequency of 2.4 GHz band and an omnidirectional pattern at higher frequency of 5.8 GHz band.
