Similarly, the influence of the stirrer on the antenna in a small reverberation chamber is much greater than that in a large reverberation chamber, and with the agitation of the stirrer, this influence is not stable, and this influence may lead to unstable working conditions of the antenna. Stablize

The small reverberation chamber excitation antenna mainly includes a monopole, a reflector and a support rod; the monopole is composed of conductive materials, and the monopole includes a cone, a disc and a conductor column; the bottom of the cone is connected to the disc, Form a whole; the surface of the reflective surface of the reflective disc is conductive, and its shape is a paraboloid; the inner surface of the disc is a plane, and the center of the inner surface is located at the focus of the reflective surface. The antenna can use the reverberation chamber to enhance the radiation of the antenna, and at the same time avoid the adverse effect of the stirrer on the antenna, and maintain a stable working state; it can also stimulate the mode of the electric field in any direction, and the transmitting antenna can achieve the best performance in the entire test frequency band. Matching, the number of excitation patterns is large, and the excitation efficiency is high.
Description
technical field [0001] The invention relates to electromagnetic compatibility testing, in particular to a small reverberation chamber excitation antenna. Background technique [0002] The purpose of electromagnetic compatibility testing is to test the sensitivity of the electrical and electronic products or systems (collectively referred to as the test pieces) to external electromagnetic fields. During the test, the test piece needs to be placed in a uniform electromagnetic field, and the test device should be shielded to avoid disturbing the external environment. The electromagnetic compatibility test usually needs to be carried out in an anechoic chamber or a reverberation chamber. Compared with the two, the test efficiency of the anechoic chamber is relatively low. With the application of a large number of new technologies such as 5G communications, autonomous vehicles, electronic tags, and power carriers, many products require comprehensive electromagnetic compatibility...
