Application of Electromagnetic Shielding Technology in the Electronic System

Abstract

With the wide application of electronic technology, electromagnetic interference has become one of the main factors to weaken electronic system performance. In communication technology and equipment, it is the development of light-duty design, low cost, high quality electronic components and electronic system that is the main object of this study. Radio frequency MEMS devices are low energy consumption, good stability. Therefore it has a strong competitiveness in the communications electronics. But EMI electromagnetic interference problem has increasingly become prominent, and based on this, this paper makes a further study on the main electromagnetic interference electromagnetic radiation of MEMS devices. In addition, this paper also establishes the mathematical model of electromagnetic radiation. Finally this paper makes an analysis and study on the shielding effect of MEMS antenna under certain magnetic materials. Through the simulation research, it is obtained that the electromagnetic effect of electronic system MEMS is good and its highest performance is more than 60 db. Whats more, shielding materials are within the range of 15 to 20 GHZ, whose shielding effects reach the maximum. The largest is close to 80 db.
