Problems solved by technology

However, in actual operation, the engineer is far away from the antenna, and it is difficult to find out whether the antenna is completely horizontal or vertical in time. When it is found, a large number of tests may have been carried out, which will greatly affect the accuracy of the test data in the laboratory. Impact

Abstract

The invention relates to a device for measuring polarization deviation of an antenna. The device comprises a fixing support , a power supply, a first wire, a second wire, a third wire, an indicating lamp and a gravity swinging piece, the fixing support is arranged on a supporting rod of a measured antenna, the power supply is arranged on the fixing support, the first wire, the second wire and the third wire are all connected with the power supply, the first wire and the second wire are both fixedly connected with the fixing support, the third wire is connected with the indicating lamp, and the gravity swing piece is connected with the indicating lamp. When the polarization direction of the measured antenna deviates, the fixing support arranged on the support rod of the measured antenna also deviates, the indicating lamp is in contact with the first wire or the second wire, and the indicating lamp is lightened.

Description

technical field [0001] The present application relates to the technical field of antenna polarization test experiments, in particular to a device for measuring antenna polarization deviation. Background technique [0002] The logarithmic periodic antenna is a kind of non-frequency variable antenna. The so-called non-frequency variable refers to the electrical characteristics of the antenna such as impedance, pattern, gain, and standing wave ratio. remain largely unchanged. The logarithmic periodic antenna is used as a device for receiving electromagnetic radiation in the radiation disturbance test of electromagnetic compatibility and the radiation spurious test of radio frequency. Log periodic antennas usually have two kinds of polarization, vertical and horizontal. When the antenna poles of different lengths on both sides are horizontal to the ground, the antenna represents horizontal polarization. When the antenna poles are vertical to the ground, the antenna is expressed...
