A printed H-plane horn antenna with loaded dielectric-metal composite lens in ka band

A printed H-plane horn antenna with loaded composite £-plane metal lens in Ka band is proposed and analyzed in this paper. The horn antenna is utilizing the Substrate Integrated Waveguide technique, which is fed by a balanced microstrip line. This antenna aperture is loaded with a series of metal-via arrays to achieve parallel metal surfaces with E-plane. The final Simulated results by CST Microwave Studio® indicate that the reflection coefficient of the antenna in 27.4–33.59GHz is lower than −10dB, the gain is 2.2dB higher than that of the antenna without the E-plane lens at 30GHz. This type of antenna can be widely used for antenna array in Ka band.
