Analyses on Related Properties of a Ridged Horn Antenna

[摘要] The ridged horn antenna is used as a kind of broadband antenna, and its application in radar engineering has become more and more extensive. And it has better standing wave and radiation characteristics in a wide frequency band. This paper analyzed the related properties of ridge waveguide and horn ridge according to the antenna structure, and gives a design method of broadband double-ridge horn antenna. According to actual needs, a dual-ridge horn antenna with a frequency range of 20GHz-26GHz was designed. And electromagnetic simulation of the antenna using HFSS was given. 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.
