摘要： 天线测量探头的性能对提升天线平面近场测量效率、最终测量结果的精度具有重要意义。针对平面近场测量的需要，应用反向四脊和差分馈电技术，设计了宽带双极化天线测量探头。对测量探头模型进行仿真，分析了带宽、方向图、隔离度和交叉极化辨识度等探头性能，确定了高隔离度、高极化纯度的宽带双极化天线测量探头的最优设计，获得了更高精度和效率的天线测量。

Abstract: The performance of the antenna measurement probe is of great significance for improving the efficiency of Planar Near-Field measurements and the accuracy of the final measurement result. Need for Planar Near-Field measurements, a wideband dual-polarized antenna measuring probe was designed using reverse quadrilateral and differential feed techniques. The measurement probe was studied by simulation. The performance of the probes such as bandwidth, pattern, isolation and cross-polarization identification was analyzed, and the optimal design of wideband dual-polarized antenna measuring probe with high isolation and polarization purity was determined. The higher antenna efficiency measurement was provided.

Key words: Probe, Wideband, Dual polarization, Antenna measurement
