Cost-effective fully-metallic geodesic H-plane horn antenna

Geodesic lenses are proposed as a compelling solution for beamforming at high frequencies due to their advantageous properties of low cost and high efficiency. Actually, the concept of geodesics is a very useful framework with many applications in different fields. Here, we propose a geodesic H plane horn antenna. The height profile of the horn antenna is modulated to alleviate the phase error and realize a directive beam. The simulation results show an enhancement of over 2.5dB in realized gain of the geodesic horn antenna compared to a planar reference counterpart.
