Abstract

The invention provides an antenna testing device, and the device is used for testing the performances of rod-shaped, bar-shaped or whip tested antennas. The device comprises a coupling antenna which is approximately set in a tubular manner, is formed through coiling in one direction and is in cup joint with the tested antenna. Two wends of the coupling antenna in the coiling direction are not closed. When the device is in use, the device can sleeve the rod-shaped, bar-shaped or whip tested antennas, and the coupling antenna is connected with a core conductor of a radio frequency line. The device can achieve the constraint-type omnibearing coupling of a radial magnetic field emitted by the tested antenna in a narrow circumferential closed space. Compared with a conventional one-dimensionaltesting device, the device has a coupling range which is not greater than 180 degrees, and is large in received energy. The coupling mode enables an induced electromotive force generated through the magnetic field coupling and an induced electromotive force generated through electric field coupling to be overlapped together, and the overlapped induced electromotive force is imported into the radiofrequency line, and a test signal is effectively enhanced.

Description

Technical field [0001] The invention belongs to the technical field of electromagnetic compatibility testing, and in particular relates to an antenna testing device for wireless performance testing of a strip, rod or whip antenna. Background technique [0002] The antenna coupling test is an important part of the electromagnetic compatibility design and evaluation of multi-antenna systems. For small antenna systems, probe type contact measurement is mostly used. This measurement method is a one-dimensional test with low coupling. Summary of the invention [0003] The purpose of the present invention is to provide an antenna testing device, which aims to solve the technical problem of low coupling in the prior art. [0004] The present invention is realized in this way. An antenna testing device is used to test the wireless performance of an antenna under test in a rod, strip or whip shape. The antenna testing device includes a substantially tubular configuration and is formed by wi...
