Comparison of conical horn with optimized corrugated surface and corrugated horn
2011
This paper is focused on comparison of two types of conical corrugated horn antennas. First antenna has a design with a simple structure which was optimized to reach minimum level of side-lobes and maximum of gain. Second antenna is a typical corrugated horn made from complex theoretical design with a complicated structure. The second antenna has minimal cross-polarization achieved by a balanced hybrid conditions between HE 1n modes accomplished by a special distribution of depth of the slots. The second antenna consists of a conical horn with the corrugated surface and a mode converter which transforms TE 11 to HE 11 mode. The mode converter is omitted in the first antenna.
