Abstract :
A modified dual mode horn antenna with rectangular aperture is proposed to improve the E/H-plane radiation pattern symmetry compared to the oversized conventional dual mode horn antenna. To verify compatibility, the conventional and the proposed dual mode horn antenna are fabricated and investigated at 15 GHz. The proposed antenna can improve the E/H-plane radiation pattern symmetry, therefore the total gain of the reflector antenna systems can be enhanced compared to a reflector antenna system with a conventional circular dual mode horn antenna.
