Poorest Man's External 2.4 GHz Wi-Fi Antenna

摘要

You can rightly argue: "why make your own Wi-Fi antenna, with all these cheap ready-made antennas available". Simply because I wanted to see how difficult it was. I also need to emphasise that this design is based on what was available and could be improved in many ways. Before we start, note that you need to be very accurate and careful with your work in order to carry out a comparison against an available antenna, for example, of the ceramic type, or other ready-made antennas. In order to have cables to use for the experiment, I bought 20 "IPX IPEX u.fl Female 1.13mm Connector Cable Single-head Adapter Connector 15cm IPX 1.13 Cable" (sic) from aliexpress.com (Figure 1).
