standard antenna

this paper studied the design principle and impedance measurement method of rfid(15693 standard) antenna.

本论文研究了射频识别（RFID）系统天线设计原理及阻抗测量方法。

Opinions vary widely on what standard defines the" tallest building in the world," whether it includes towers or antenna or neither in the measurement of height.

关于如何认定“世界上最高建筑”的标准各种各样，在高度的测量上是否要包括塔或天线，亦或两者都不包括。

During experiment researches, an impedance converter is designed to connect the standard port with the antenna input port, and the method of comparing with standard linear polarized antenna is used to measure array antenna circular polarized gain.

在实验中，设计了用于连接标准接口和天线输入口的阻抗变换器，对阵列天线辐射特性的测量采用了标准线极化天线比较法。
