Abstract

The invention discloses a broadband receiving and transmitting sharing type coaxial waveguide duplexer, and belongs to the technical field of microwave antennas. The filter comprises a low-frequency-band coupling waveguide, a short circuit plate, a turnstile, an E-plane T-type synthesizer and a waveguide load, the coaxial waveguide outer waveguide is provided with a coupling hole for transmitting low-frequency signals, the coupling hole is connected with the low-frequency coupling waveguide, the coaxial waveguide outer waveguide is further provided with a slot for placing the short circuit piece, the slot and the coupling hole for transmitting the low-frequency signals form an included angle of 90 degrees, and the coaxial waveguide outer waveguide is connected with a round port of the turnstile. The coaxial waveguide inner waveguide is placed in the coaxial waveguide outer waveguide and the turnstile structure, and the axes of the coaxial waveguide inner waveguide and the turnstile structure coincide; the turnstile is provided with four coupling ports, two ports which are in polarization orthogonality with the coupling holes for transmitting low-frequency signals are synthesized by an E-plane T-type synthesizer, and the other two ports are connected with a waveguide load. The antenna has the characteristics of compact structure and miniaturization, and can meet the application of a small-caliber receiving and transmitting common antenna under the condition of the same working frequency band.

Description

technical field [0001] The invention relates to the technical field of microwave antennas, in particular to a coaxial waveguide duplexer for wideband transmission and reception. Background technique [0002] With the rapid development of science and technology, the application of satellite communication has become more and more extensive. Due to the extreme shortage of frequency resources, the bandwidth of satellite communication reflector antennas can be expanded by using various multiplexing technologies, and satellite communication can achieve multiple Common use of frequency bands, these functions are mainly completed by the feeder system. At present, satellite communication antennas are developing in the direction of multi-polarization, multi-band, broadband, etc., and at the same time, they must meet the requirements of miniaturization, light weight, and low cost. [0003] The waveguide feeding device is an important part of the feeding system. In modern communication...
