Embodiment Construction
[0017] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0018] Such as figure 1 with figure 2 As shown, the ultra-short waveguide load of the present invention includes a flange 31 and a load absorbing sheet 33, a groove is opened in the middle of the flange 31, the load absorbing sheet 33 is located at the bottom of the groove, and the load absorbing sheet 33 and the flange 31 Upper face (see figure 1 Shown is the cavity between the groove walls of the groove) to form the waveguide cavity 34, and the thickness of the load-absorbing sheet 33 and the empty waveguide cavity 34 adds up to be equal to the depth of the groove (see figure 2 shown). Both the groove and the load-absorbing sheet 33 are circular, which greatly improves the absorption capacity of the load-absorbing sheet 33, and is easy to process and manufacture. The preferred form of the waveguide cavity is that the periphery of the load...

The invention discloses an ultrashort waveguide load. The ultrashort waveguide load comprises a flange disc and a load suction sheet, wherein a groove is arranged at the middle part of the flange disc; the load suction sheet is located at the bottom of the groove; the thickness of the load suction sheet is smaller than the depth of the groove; and the cavity between the external end surfaces of the load suction sheet and the flange disc forms a waveguide cavity. The ultrashort waveguide load has the advantages that: the load suction sheet and the waveguide cavity are integrated in a metal flange disc, and the flange disc is wrapped outside the entire load, so that the end surface of the load suction sheet and the end surface of the flange disc form a round waveguide cavity, thus the suction capability of the suction sheet is greatly improved and good electrical performance can be achieved, and test proves that the standing wave ratio can reach below 1.3; and the integral size of the ultrashort waveguide load is the external shape size of the metal flange disc, so that the integral size is small, and good electrical performance can be achieved under the condition of extremely small thickness size of waveguide load.
Description
technical field [0001] The invention relates to communication equipment components, in particular to an ultrashort waveguide load. Background technique [0002] The waveguide matching load is the terminal device of the waveguide system. It fully absorbs the microwave power transmitted along the waveguide without reflection or radiation to the surrounding space. [0003] The necessity of applying a matching load is obvious. When adjusting the instrument and radar, using it as a false antenna can avoid space radiation of electromagnetic waves, avoid exposing the target, is conducive to confidentiality, and can also avoid interference to other equipment; in engineering applications Among them, the load can be connected to the unused port to protect the transmitter, and at the same time avoid signal leakage from interfering with other equipment. It can be used on the receiving part to avoid the influence of useless signals on the system. [0004] At present, waveguide load gene...
