40.5-42.5 GHz Band Antenna Based on the Dielectric Resonator Using Whispering Gallery Modes

Abstract

It is proposed to use a whispering gallery mode dielectric resonator with a segmental curved surface as mm-wave omnidirectional antenna with a multi-lobe radiation pattern in the azimuthal plane. The directions of the maxima of the lobes of the diagram can be shifted by a small change in frequency. This makes it possible to form a pie chart and cover the entire sector of angles 0 … 360 degrees. The antenna is made of Teflon. The measurements of the parameters of the radiation pattern have been carried out. The dependences of its shape on frequency are obtained.
