High side lobe suppression millimeter wave antenna with a cylindrical-parabolic reflector

Concept, simulation, design and realization of the printed tapered antenna array with a subreflector and a cylindrical-parabolic reflector is presented. This antenna is intended for microwave and millimeter wave ranges and is characterized by many advantages such as efficacy, compactness and possibility of integration with other passive and active microwave circuits. Antenna gain is nearly 26 dBi and aperture efficiency is almost 50%. The antenna operates in the frequency range around 26 GHz. Measured results are in good accordance with those obtained by a simulation.
