遥控接收机天线匹配电路设计及仿真
|
摘要
针对车载遥控接收机天线馈电端口不匹配的情况,利用电磁仿真软件FEKO对天线馈电端口的驻波比、输入阻抗进行仿真分析。由匹配电路设计软件ADS得到分立LC匹配电路,并在FEKO软件中通过非辐射网络来模拟天线的匹配电路,实现天线匹配网络与天线的一体化仿真。仿真表明,遥控接收机天线馈电端口的驻波比由3.96降至1.5以下。
Aiming at the mismatch of the antenna feed port of the vehicle remote control receiver,the standing wave ratio and input impedance of the antenna feed port are simulated and analyzed by FEKO software.The discrete LC matching circuit is obtained by ADS software,and the matching circuit of antenna is simulated by non-radiation network in FEKO software.The integrated simulation of antenna matching network and antenna is realized.The simulation results show that the standing wave ratio of antenna feed port of remote control receiver is reduced from 3.96 to less than 1.5.
