Zheng Ting-l · Science Technology and Engineering · 2014
On the coupling performance of LC resonance mutual inductance coupling system is mainly researched. The relationship between the coupling factor and the distance,coil size is analyzed through the planar spiral inductor mutual inductance model. Multiple inductance coils of different parameters are designed and fabricated,and when the sensor size is fixed with the environmental restrictions,the increase of coil inner diameter,the decrease of number of turns( line width and line spacing is certain) and the decrease of line width,line spacing and coil inner diameter( the number of turns is certain) can effectively improve the coupling factor,as well as the transmission efficiency of mutual inductance coupling system,which is benefit for the acquisition of LC resonant sensor signal and laid a solid foundation of LC resonant sensor application in high temperature,high pressure harsh environment.
