PCB WIFI directional antenna

Overview

When I was watching videos, I saw that KREOSAN had made a WIFI directional antenna, and I also saw that other people in China had done it, so I decided to give it a try. I saw that other people were using the same copper plates as the original author, so I went to Xobao to look at the copper plates. The price feels a bit expensive, and the finished laser-cut product is also very expensive, so I plan to use PCB to make one. The original author said that the thickness of the copper plate and the diameter of the screw do not affect the final effect. The PCB copper foil is also copper, and the PCB processing precision is high. This is exactly what I wanted. Before I even built the board, I used PCB to try it out.
