two-wire antenna

The concept of equivalent radiated power is explained based on the principle of space power synthesis, the requirements of equivalent radiated power test on site and antenna erection are analyzed, and two kinds of sites meeting different operation requirements are presented.

从空间功率合成的原理出发解释了等效辐射功率的概念，分析了等效辐射功率测试对场地和天线架设的要求，给出了满足不同使用需求的两种测试场地。

These two models of antenna apply well in UHF RFID reader, and the technology of air cavity will achieve better development.

应该说这两款天线都能很好的应用在超高频段RFID读写器中，而空气腔技术势必会有更大的发展。
