- Abstract
- In this paper, a Rotman lens of multi-beam feed that can be applied to a car collision avoidance radar in the millimeter wave frequency was designed using nonradiative dielectric (NRD). 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 optimized so as to minimize sidelobe of array factor. To prevent beam pattern from being distorted, multiple-reflection from sidewall has been eliminated by a corrugated sidewall.
