ABSTRACT:
The present invention provides a new class of hybrid-mode horn antennas. The present invention facilitates the design of boundary conditions between soft and hard, supporting modes under balanced hybrid condition with uniform as well as tapered aperture distribution. In one embodiment, the horn antenna (100) is relatively simple mechanically, has a reasonably large bandwidth, supports linear as well as circular polarization, and is designed for a wide range of aperture sizes.
