摘要
在无法直接接触测量信号的场合,采用无线耦合方式进行信号传输与测试,对无线耦合信号传输天线进行参数设计,通过ADS软件对电感为4μH、中心频率为7.812 MHz的天线阻抗匹配设计进行仿真,搭建阻抗匹配电路,比较匹配前后天线端测试信号变化,优化天线阻抗匹配网络。
In the occasion of no direct contact measured signal, the wireless coupling transmitting is used and the signal is tested, and the transmission antenna＇ s paranleters are calculated. The ADS software is used to match the antenna impedance for the inductance of 4 μH at the center frequency of 7. 812 MHz, and the impedance matching circuit is structured, and the test voltage changes before is compared with after the antenna impedance matc- hing. The antenna impedance matching network is optimized.
