Abstract

A new omnidirectional antenna for mm-wave applications is suggested. The antenna is in the form of monopole mounted on a conical circular reflector with smooth edges and a small pedestal in the middle. Following design procedure is suggested: (a) the main beam is positioned to the desired angle by changing the angle of the cone reflector, (b) the sidelobes are influenced by optimizing the pedestal. By using suggested design procedure two antennas operating in the range from 57 GHz to 63 GHz are modeled: (a) an antenna for broadband radio channel measurements, and (b) an indoor base station antenna with cosecant radiation pattern. The antennas are fabricated and measured. Good agreement between simulated and measured results is obtained
