ABSTRACT

The horn antenna has large bandwidth, superior directionality, easy design and processing, and high gain. It has become an ultra-wideband antenna that can be practically applied in many occasions. The ridged horn antenna has an ultra-wideband, wide-band, uniform pattern. Moreover, it has a higher gain and is widely used as a feed of a high gain antenna or an array element of an array antenna. This paper introduces the structural characteristics of the double-ridged horn antenna from many aspects, and designs a double-ridged horn antenna. And through electromagnetic simulation of HFSS, the results show that the double-ridged horn antenna has good directivity in the frequency range of 20GHz~26GHz. The results showed that the gain reaches 18 dB at 24 GHz, and the main flap of the three-dimensional gain pattern is not cracked.
