摘要

这项工作调查了大量测试人员的平均有效增益(MEG)的变化，以找出解剖结构和戴眼镜等人的差异对MEG(即相对于参考的接收信号功率)的改变程度。评估是在一个典型的GSM-1800城市微型蜂窝中进行的，基站位于室外，距离手机约700米。手机被放置在类似办公室的环境中。不同人之间的MEG峰值变化大于10 dB，指示贴片天线的“无人”和“有人”之间的差异平均为3 dB，鞭状天线为6 dB，螺旋天线为10 dB。

Measured variation in performance of handheld antennas for a large number of test persons

This work investigates the variation in the mean effective gain (MEG) for a large number of test persons in order to find how much the difference in anatomy and persons who wear glasses, etc., changes the MEG (i.e., the received signal power with respect to a reference). The evaluation was carried out in a typical GSM-1800 urban micro cell with the base station located outdoor approximately 700 m from the mobile. The mobile was located in office like environments. Peak variations in the MEG among different persons of more than 10 dB were found and the difference between "no person present" and a person present is on the average 3 dB for a directive patch antenna, 6 dB for a whip antenna and 10 dB for a helical antenna.
