Abstract

The invention discloses an ultra wide band electric field probe using a U-shaped structure. The ultra wide band electric field probe includes arc edge reference planes, a U-shaped signal line, an intermediate signal line and a top layer signal line. The arc edge reference planes include a top layer reference plane and a bottom layer reference plane, and the top layer reference plane and the bottomlayer reference plane are correspondingly of symmetrical similar 'T' shape structures in the central line of the plane of the probe. The U-shaped signal line is located between the top layer reference plane and the bottom layer reference plane, and a narrow handle end located on the intermediate layer of the probe is a transmission line of a strip line structure. Two arms of the open end of the U-shaped signal line are distributed symmetrically in the center line of the plane of the probe. The arc end of the U-shaped signal line is connected with the intermediate layer signal line, and the intermediate layer signal line is connected to the top layer signal line through a connecting hole. The ultra wide band electric field probe has the characteristics of ultra wide band and high sensitivity, the defect that in a traditional test, signals of weak electric fields and ultra wide band testing are not measured are effectively improved, and veracity of testing results is ensured.

Description

【Technical field】 [0001] The invention belongs to the field of electromagnetic field testing, and particularly relates to a U-shaped electric field probe structure for ultra-wideband near-field testing with a frequency bandwidth of 9KHz-40GHz, that is, the near-field electric field distribution parameters of the equipment under test can be obtained by performing near-field testing with the probe. 【Background technique】 [0002] With the rapid development of science and technology, the wide application of large-scale integrated circuits and the increasing operating frequency of circuits, every module and even every section of wiring in electrical equipment may be a source of electromagnetic interference. Electromagnetic interference not only affects the normal operation of the system, but also may cause serious accidents in severe cases. In recent years, countries around the world are actively formulating standards and norms to promote the effective protection of electromagne...
