Problems solved by technology

However, the shape of the waveguide element is relatively large, and it occupies a large volume. When the space is small, it adds weight to the system and brings inconvenience to the installation.
[0003] According to the microwave transmission theory, when the rectangular waveguide transmits the TE10 mode signal, the waveguide port of a certain size corresponds to the corresponding start frequency and stop frequency, and the signal cannot be transmitted smoothly outside the start frequency and stop frequency

Abstract

The invention relates to a miniaturized waveguide component comprising a waveguide and a cable fixed on a second wide side thereof. A waveguide cover is assembled at the top end inside the waveguide.The waveguide is filled with a dielectric material therein. A tuning component is arranged on a first wide side of the waveguide. A probe is fixed on a core wire inside the cable. According to the invention, as the waveguide is filled with the dielectric material therein, the size of the waveguide opening can be reduced while the transmission frequency range is ensured not to be reduced, therefore, the overall size and occupation volume of the waveguide component are substantially reduced, the installation of the entire waveguide component in a narrow space is facilitated, and the weight of the system can also be reduced.

Description

【Technical field】 [0001] The invention relates to the field of microwave transmission technology, in particular to a miniaturized waveguide element. 【Background technique】 [0002] The waveguide system is widely used in microwave transmission systems due to its advantages of large power capacity and small attenuation. Especially when transmitting high-power signals, the waveguide system is usually selected for microwave signal transmission. However, the shape of the waveguide element is relatively large, and it occupies a large volume. When the space is small, it adds weight to the system and brings inconvenience to the installation. [0003] According to the microwave transmission theory, when the rectangular waveguide transmits TE10 mode signals, the waveguide port of a certain size corresponds to the corresponding start frequency and stop frequency, and the signal cannot be transmitted smoothly outside the start frequency and stop frequency. In other words, once the oper...
