A novel dual polarization antenna array fed by a dual mode non-radiative dielectric waveguide

Abstract

This paper presents the design and implementation of a dual polarization antenna with a low loss, planar feeding structure applicable for both, communication and radar applications at mm-wave frequencies. The array and feed network efficiency is approximately 50 %. Radiation patterns are given and discussed in detail. A higher gain can be achieved by duplicating the feed structure and the antenna subarrays.
