摘要

本文介绍了一种测量小型器件辐射效率的改进方法。该方法基于惠勒原理，在两个受控环境中测量天线阻抗:自由空间和封闭的金属盒。介绍了一种扩展等效电路，精确地描述了金属盒内小器件的行为。该模型是确定辐射效率的基础，与盒子的大小和设备在盒子内的位置无关。在本文的下一部分，提出了一种用于GSM移动电话的集成最新多波段天线的概念。用上述方法表征辐射效率，证明了表征效率的新方法。

Improved radiation efficiency measurement of mobile systems and application to a novel multiband antenna

In this paper an improved method for measuring the radiation efficiency of small devices is introduced. The method is based on Wheeler's principle of measuring the antenna impedance within two controlled environments: free space and a closed metallic box. An extended equivalent circuit is introduced, that gives an exact description of the behavior of the small device within the metallic box. This model is the basis for the determination of the radiation efficiency, independent of the size of the box and the location of the device within the box. In the next part of the paper, a concept for an integrated up-to-date multiband antenna for a GSM mobile phone is presented. The characterization of the radiation efficiency by the above mentioned method proves the new way to characterize the efficiency.
