摘要
阐述TD-SCDMA智能天线校准网络工作原理,设计一种TD-SCDMA八单元直线阵的校准网络,通过比较提取的各单元天线端口处信号的幅值和相位,获取各单元天线所需的偏置量.采用AnsoftHFSS和Microwave office软件构建校准网络仿真模型.仿真结果表明,校准参数中的耦合度和幅相一致性均满足行业标准要求,与成品测试结果一致.
The principle of a calibration network of TD-SCDMA smart antenna array was described.A calibration network of eight-element linear array of TD-SCDMA smart antenna was designed.By comparing the amplitudes and the phases extracted from each antenna element port,the offset values were obtained.Simulation model was built using Ansoft HFSS and Microwave office software.Simulation results show that the coupling degree and identity of the amplitude and phase comply with industry standards and measurement data of p...
