移动通信系统室内分布天线测试方法的研究

摘要

In order to deal with deifciencies of bad accuracy, poor repeatability and low efifciency of existing test methods of the indoor distributed antenna, two solutions were presented to provide scientiifc and feasible data references to the measurement of the indoor distributed antenna test. Firstly, a novel far-field measurement method was presented whose effectiveness was veriifed with results that the method has advantages of high accuracy, efifciency and lfexibility. Then, a new kind of test ifxture was presented. Practical results show that the new test ifxture has superiorities of the accurate measurement, good repeatability and convenience. The presented method is suitable for both near-ifeld and far-ifeld tests.%为了解决室内分布天线现有测试法存在的准确性差、重复性差以及测试效率低的问题，提出了两种方案，为科学合理地进行室内分布天线测试提供了数据依据。首先提出了一种新的远场测量法，并对该方法的有效性进行了验证，结果表明新方法不仅测试准确度和测试效率高，而且灵活度高；然后提出了一种新的测试工装，通过实测结果表明，新工装具有对测量影响小、重复性好、使用方便等优点，该工装既可应用于近场测试中，也可应用于远场测试中。
