Abstract

The invention discloses an attenuator, and belongs to the technical field of microwave attenuators. The attenuator comprises a polarization grid mesh and a rotating table, the polarization grid mesh comprises a metal wire frame and a grid mesh fixedly connected with the metal wire frame, the grid mesh comprises a plurality of molybdenum wires which are arranged side by side in parallel at equal intervals, the rotating table is used for driving the polarized grid mesh to rotate so as to change the included angle between the molybdenum wires and the vector direction of an electric field generated by electromagnetic waves, the distance between every two adjacent molybdenum wires ranges from 500 micrometers to 800 micrometers, and the diameter of the polarized grid mesh is not smaller than 1 m. The attenuator improves the attenuation range of low-frequency-band microwaves.

Description

technical field [0001] The invention relates to the technical field of microwave attenuators, in particular to an attenuator for accurately attenuating space transmission signals. Background technique [0002] An attenuator is a device that provides attenuation in a microwave test system. It can produce a certain amount of attenuation in the microwave power and then output it. It is widely used in electronic equipment such as control power transmission and radar systems. The traditional coaxial attenuator is closely related to the working frequency. Under the same conditions, the attenuation value of different frequencies is different. At the same time, the temperature will greatly affect the value of this type of attenuator. Under different ambient temperatures, the attenuation value changes. And the coaxial attenuator works in the shielded transmission line, and attenuates all signals in the transmission line. The attenuation of the waveguide form, the working frequency i...
