摘　　要：无源互调(PIM)是一个吸引众多领域研究人员的课题,包括卫星、天线和智能终端等。本文提出一个非接触式PIM测量的新思路:使用一个经过近场重构的基片集成缝隙波导(SISW)作为互调信号的激励和接收路径,SISW通过对载波信号的远场抑制和近场测试区的优化,实现了一种针对没有射频端口的样品非线性特性的评估解决方案。该测试平台结合了近场天线的有限辐射特性和多敏度测试区在PIM评估中对收发系统和测试样片的适应性。实验结果表明,该测试方法在稳定性和分辨力方面具有相当大的工程应用潜力。Passive Intermodulation(PIM)is a subject that attracts researchers in many fields,including base station antennas and satellites.In this work,a new setup for non-contact PIM measurement is proposed,which takes a Substrate-Integrated Slotted Waveguide(SISW)designed by field reconstruction as the excitation and reception path.The SISW with field reconstruction enables a solution for the evaluation of the non-linear characteristics of samples without RF ports through far-field suppression and near-field partitioning of the carrier signal.The proposed test platform combines the finite radiation characteristics of near-field antennas and the adaptability of the gradient test area to transceiver systems in the PIM evaluation.The experimental results suggest that the proposed test method presents considerable potential for application in terms of stability and resolution.
