摘要

本文描述了一种可以在运动场上使用低成本设备实现的天线特性测量技术。这是对反射范围测量的调整，并将结果与在开放区域试验场和消声室中进行的对照测量进行了比较。该技术能够获得精度在天线方向图的瞄准线增益的2dB以内和主波束的2dB之内的结果。它的目的不是要高度准确，而是要表明，可以以成本敏感的方式向学生介绍射频设备，以及在高等教育机构使用学生自制天线的预表征测试方法。

A cost-sensitive technique to pre-characterize UHF antennas at tertiary education institutions

This article describes an antenna characterization measurement technique that can be achieved using low-cost equipment on a sports field. It is an adaptation of a reflection range measurement and results were compared to control measurements done at an open-area-test-site as well as in an anechoic chamber. This technique was capable of obtaining results with accuracy to within 2 dB for boresight gain and within 2 dB for the main beam of the antenna pattern. Its purpose is not to be highly accurate, but rather to show that it is possible to cost-sensitively introduce students to radio frequency equipment, as well as have access to a pre-characterization test method for inhouse, student-built antennas at tertiary education institutions.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
