摘要

近年来发展起来的无源未知双端口天线模型用于研究天线的损耗和失配特性。先前的工作表明，双端口天线模型可以用混响室中单个天线的数据来确定天线传输效率的下限。这种计算的局限性在于，它依赖于在双端口天线模型中所做的假设，并且只提供了天线效率的下限。其中一个必要的假设是，混响室中的搅拌器至少在几个位置上是完美反射的。

A lower bound of antenna efficiency based on the two-port model: How close is it?

The passive, unknown two-port antenna model that has been recently developed is used to investigate the loss and mismatch characteristics of an antenna. Previous work has shown that the two-port antenna model can be used to determine a lower bound of the antenna's transmitting efficiency with data taken from a single antenna in a reverberation chamber. The limit of this calculation is that it relies on assumptions made in the two-port antenna model and provides only a lower bound of the antenna's efficiency. One of the necessary assumptions is that the stirrer in the reverberation chamber is perfectly reflecting for at least a few positions.
