| 摘 要： | 采用电磁仿真软件FEKO分别建立单、双天线激励混响室仿真模型，通过计算混响室测试区域电场标准偏差值研究混响室场均匀性。研究表明：与单天线激励混响室相比较，混响室工作于双天线激励条件时，测试区域各轴向电场标准偏差平均下降了15．3％，总标准偏差下降了21．9％，改善了测试区域场均匀性，这说明双天线激励混响室可提高场均匀性，同时利用双天线的功率合成解决了混响室大功放问题。

| Abstract: | The simulation model excited by two antennas or one antenna was constructed and analyzed with FEKO. The field uniformity was analyzed by calculating the standard deviation of the electric field in a reverberation chamber. Compared with the reverberation chamber excited by one antenna, the standard deviation of every axis in the reverberation chamber excited by two antennas decreases by 15.3%,the whole--deviation decreases by 21.9%,and the field uniformity is improved. The problem of high power amplifier is resolved by using two antennas. |
