Design of a cylindrical resonant cavity antenna for BAN applications at V band

Abstract

An antenna for on-body applications based on a cylindrical resonator is presented in this paper. The antenna is designed to work at V-band, specifically in the unlicensed bandwidth around 60GHz.The resonant cavity is obtained by means of a woodpile Electronic Band Gap (EBG) structure made of alumina, and exhibits an omnidirectional radiation pattern on the plane normal to the cylinder axis. Such characteristic is extremely important for on-body application, since it improves the signal coverage of the human surface while reducing the energy lost in off-body radiation.
