摘要

本文提出了一种用于近场测量的灵敏微型超宽带探头。该探头采用新型 V 形尖端设计和斜坡结构，具有更好的场分布和阻抗匹配，带宽范围从 10 kHz 到 52 GHz，与超宽带应用兼容。拟议的电子探针制造工艺采用四层印刷电路板（PCB），使用罗杰斯 RO4003 (tm) 和 RO4450 高性能电介质，εr 分别为 3.55 和 3.3。探头长度为 40 毫米，最小宽度为 4 毫米，适用于狭窄、复杂和集成的印刷电路板。在 2 GHz 和 40 GHz 时，无源 E 探头的灵敏度分别为 -106.29 dBm 和 -87.48 dBm。它的空间分辨率非常小，在 20、25、30 和 35 千兆赫时为 0.5 毫米。该探头体积小、价格便宜，可以诊断遥测、无人机和航空电子设备等电子系统中的电磁干扰（EMI）。

A Miniaturized Ultrawideband V-Shaped Tip E-Probe for Near-Field Measurements

A sensitive, miniaturized, ultrawideband probe is proposed for near-field measurements. The proposed probe is based on a new V-shaped tip design and a slope structure resulting in better field distribution and impedance matching with a span bandwidth from 10 kHz up to 52 GHz, which is compatible with ultrawideband applications. The proposed E-probe fabrication process utilizes a four-layer printed circuit board (PCB) using Rogers RO4003 (tm) and RO4450 high-performance dielectrics, with εr = 3.55 and 3.3, respectively. The probe length is 40 mm with a minimum width of 4 mm, which is suitable for narrow, complex, and integrated PCBs. The passive E-probe sensitivity is −106.29 dBm and −87.48 dBm at 2 GHz and 40 GHz, respectively. It has a very small spatial resolution of 0.5 mm at 20, 25, 30, and 35 GHz. The probe is small and cheap and can diagnose electromagnetic interference (EMI) in electronic systems such as telemetry, UAVs, and avionics.
