EMC near field probe

Overview

This is an EMC near-field probe, used to detect interference sources on circuit boards. It needs to be used with an SDR receiving rod. It has obvious effects without a preamplifier. The PCB board is 1.6mm thick, otherwise the SMA connector on the side cannot be welded perfectly. The transmission line on the PCB has an impedance design, and it is calculated using Jialichuang's software. There is no actual test, so I don't know if the calculation method is correct.
