Embodiment 1

[0021] Such as figure 1 Shown is the structural representation of the waveguide load 10 in Example 1 of the present invention Figure 1 . It can be seen that the waveguide load 10 is composed of a waveguide 13 for transmitting microwave signals, an absorber 12 arranged inside the waveguide 13 for absorbing a part of the microwave signal, and openings a1 and Opening a2. At the same time, a waveguide flange 14 is provided at the opening a2, and the waveguide flange 14 is connected to the waveguide 13 by welding for connecting with other first microwave components (not shown in the figure). The opening a1 at the other end is directly open to the external space. Wherein, the absorber 12 is arranged at a predetermined position inside the waveguide 13, and it can absorb 50% to 95% of the microwave signal, while the remaining part of the microwave signal leaks out from the opening a1 at the other end, and makes the leakage The outgoing microwave signal can be received by a second...

Embodiment 2

[0027] image 3 Shown is a schematic structural diagram of the waveguide load in Example 2 of the present invention. When the waveguide load 20 is used in an open-air environment, the transmission of microwave signals in the communication system will be affected due to rainwater entering the load. Therefore, a waterproof end cover 31 is added at the opening a1 of the other end of the waveguide load 20 to protect the waveguide load 20 . Moreover, the end cover 31 is made of a material with wave-transmitting properties. The end cover 31 can be in any shape, and covers the opening, and is connected to the waveguide 13 by screw fixing, glue bonding and other ways. When the end cover is connected to the waveguide by screws, waterproof glue can be used, which can play a waterproof and dustproof role.

Abstract

The invention provides a waveguide load which comprises a waveguide tube and an absorber. The waveguide tube is used for transmitting microwave signals, the absorber is arranged in the waveguide tube and used for absorbing a part of the microwave signals, openings are arranged at two ends of the waveguide tube, a flange is arranged at one end of the waveguide tube and used for being connected with another first microwave element, the opening at the other end of the waveguide tube is open to a space and is spaced from another second microwave element by a certain distance, and the absorber is arranged at a specified position, so that energy of the microwave signals leaking out from the opening at the other end of the waveguide tube is received by the microwave element. The absorber can absorb 50-95% of the microwave signals, and the residual microwave signals leak from the opening at the other end of the waveguide tube and are received by the second microwave element.

Description

technical field [0001] The invention relates to a waveguide load, in particular to a waveguide load with the function of leaking microwave signals. Background technique [0002] Microwave components called waveguide loads are often used in the microwave field, including matched loads, mismatched loads, and so on. Among them, the matching load is one of the most commonly used components. It is a single-port component that can absorb almost all input power. It is generally composed of a waveguide and a material that can absorb microwave power. It is used to realize a certain part of the system. While presenting a traveling wave state, it can also absorb useless signals. In communication systems and microwave measurement systems, it is often necessary to match loads to establish the traveling wave state of the system. There is also a mismatch load similar to the matched load structure, but the size is slightly changed. It can absorb part of the microwave power and reflect par...
