摘要
手机天线的辐射性能直接影响着通信的质量,快速准确测试其性能具有十分重要的现实意义。本文依据CTIA的测试标准,重点分析了天线等效全向辐射功率(EIRP)测试的基本原理,并利用标准的全微波暗室及相关测试仪器组建了测试平台,在此基础上研究设计了一个基于GPIB的EIRP自动测试软件。该软件可以实现EIRP的快速准确自动测量,计算手机总辐射功率(TRP)和效率,绘制三维辐射方向图,并依此判定手机天线辐射性能。整个软件用户界面设计友好,大大的提高了手机天线的测试效率。
The radiation performance of mobile antenna plays an important role in wireless communication; therefore it is very important in engineering to test the antenna performance rapidly and accurately. According to Cellular Telecommunications ＆ Internet Association （CTIA） certification program, the test principle of effective isotropic radiated power （EIRP） is studied in the paper. Then a test platform is established using anechoic chamber, spectrum analyzer, digital radiocommunication tester CMD55 and other test equipment. Further, a test software for the automatic test system is designed cautiously, which is based on GPIB and can be used to test EIRP rapidly, calculate the total radiated power （TRP） efficiency and draw the 3D antenna radiation pattern. The test results can be used to judge the radiation performance of mobile antenna. In addition, the designed software features a user-friendly interface and improves the test efficiency greatly.
