摘　　要：对于普通的仿真暗室,由于很难避免仿真测试和天线方向图近场测试的相互影响,所以一般无法在该类暗室内完成天线近场测试。对于尺寸大、结构独特的仿真暗室,提出了它的综合利用问题,天线近场测试就是其中之一。介绍了天线近场测试技术,结合仿真暗室特点,提出了在仿真暗室中组建一套天线近场测试系统,并给出了详细的位置布置方案。通过分析仿真试验与天线近场测试的相互影响,认为可以在该仿真暗室完成非车载天线以及部分车载天线的近场测试。Antenna near-field test may not be accomplished in ordinary simulation anechoic chamber owing to each other influence between simulation test and antenna near field test There are some simulation anechoic chambers of which dimension is very big and structure is unique,so we present the issue of integration application. The pattern of antenna near-field test is one of it. The technology of pattern of antenna near-field test is introduced. Grounded on simulation anechoic chamber,we bring forward that an antenna near-field test system is designed in simulation anechoic chamber, and the detailed station project are put forward. According to analyzing each other influence between simulation test and antenna near field test was, we deem that in simulation anechoic chamber antenna near-field test about the antenna which is not placed on motor and some antennas which is lay on the motor may be accomplished.
