    Abstract

    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.
