Abstract

In this paper, a small omni-directional EMI test antenna with special design is introduced. By selecting the electrical performance parameters of the antenna magnetic substrate, the antenna could be effectively miniaturized. At the same time, based on the antenna optimization design technology, the radiation characteristics of the antenna within the working frequency band could also be ensured. Finally, through the optimization of various parameters, the antenna size is no more than 50mm*45mm*45mm, gain is no less than -5dbi and the radiation in Y-Z plane is omnidirectional. The research and development of the antenna has certain significance for the EMC test in RF band.
