Design of a nonradiative dielectric Rotman lens in the millimeter wave frequency

Abstract

In this paper, a Rotman lens for a multi-beam feed that can be applied to a car collision avoidance radar in the millimeter wave frequency range was designed using nonradiative dielectric (NRD) guide. NRD guide at the output ports was designed to obtain low loss, small coupling between the output ports, and dominant mode operation. The Rotman lens is… (More)
