High-/spl epsi/. LSE-NRD guide radiator array at 35 GHz

A technique for construction of a millimeter-wave antenna was developed based on the high permittivity NRD guide. The novelty of the present technique lies in the use of simple radiator, which consists of a tapered dielectric strip of simple structure having good compatibilities with millimeter-wave integrated circuits. Since the radiator has a broad radiation pattern, a new type of array antenna structure was successfully fabricated.
