Four-ridge horn antenna and processing method thereof

Abstract

The invention relates to a four-ridge horn antenna and a processing method. The four-ridge horn antenna comprises a horn main body, four ridge pieces, a probe and a short-circuit board, wherein the four ridge pieces are sequentially, uniformly and circumferentially arranged on an inner cavity of the horn main body at interval, the four ridge pieces and the horn main body are of an integral forming structure, a tail part of the horn main body is connected with the probe, the probe penetrates through the horn main body in a radial direction, and the tail part of the horn main body is connected with the short-circuit board. In the four-ridge horn antenna proposed by the antenna, the four ridge pieces and the horn main body are of the integral forming structure, the four-ridge horn antenna is simple in structure, is good in quality and high in accuracy, and has favorable antenna electrical property, a processing and assembly error is effectively avoided, and the four-ridge horn antenna is applicable to application development demands of a millimeter-wave horn antenna for high performance and high reliability.

Description

technical field [0001] The invention relates to the field of radio technology, in particular to the field of microwave horn antenna processing technology, in particular to a four-ridge horn antenna and a processing method. Background technique [0002] Horn antennas are widely used in microwave measurement, radar, and detection systems due to their versatility, simplicity, and good radiation performance. Recently, with the development of electromagnetic wave theory and antenna technology, today's electronic countermeasures, electronic reconnaissance and other electronic systems have an increasing demand for broadband horn antennas. The most direct way to widen the working frequency band of the horn antenna is to use the waveguide and The upper end of the horn antenna is opened / opened to join the ridge structure. This ridge horn antenna has the advantages of high gain, low impedance, small size, and easy connection with transmission lines. It is very suitable for radar, elect...
