摘要

提出了一种新颖的无相近场测量方法。利用两个共面探头同时扫描平面近场表面接收到的强度平方数据，检索近场相位并进行近场/远场变换。与现有的相位检索技术相比，该方法需要更少的扫描时间和低成本的设备。对SAR应用的微带贴片天线进行了测量，作为该方法的实验验证。

An integrated probe for planar near-field only intensity measurements

An innovative procedure for phaseless near-field measurements is presented. The squared intensity data received by two co-planar probes simultaneously scanning a planar near-field surface are used to retrieve the near-field phase and subsequently to perform the near-field/far-field transformation. The approach requires reduced scan times and low-cost facilities, when compared with existing phase retrieval techniques. Measurements on a microstrip patch antenna for SAR applications are used as experimental validations of the method.
