Abstract
An integrated multi-beam antenna with a shared dielectric lens is disclosed. The antenna is formed by positioning the feed apertures of a plurality of waveguide feeds at positions located on the surface of the shared dielectric lens. The angular direction and shape of radiation beams produced by the waveguide feeds are determined by the physical and dielectric characteristics of the lens, the location of feed apertures of the waveguide feeds on the surface of the lens, and the frequency of electromagnetic energy propagating in the waveguide feeds. The principles of the invention are applied to realize an inexpensive, integrated multi-feed antenna adapted to provide desired angular areas of coverage for both a long range and short range radar in an automotive radar safety system.
