Majority of the audience are likely acquainted with the idea that one effective method to expand the reach of wireless fidelity is by utilizing an improved antenna for those 2.4 gigahertz signals. However, at the same time, engaging in such high-frequency adventures is known to be somewhat challenging. [Dereksgc] decides to challenge that notion by constructing a spiral-shaped wireless fidelity antenna — and if that was not adequate — he also decides to test it in a real-world scenario. Is there any other way than testing it in a real field?
The two videos have been placed below the break, and you can access his spiral antenna calculator on his website and the parametric CAD file for the structure on his GitHub repository. Initially, he imparts a brief lesson on the essentials of spiral antennas before delving into the assembly process, which also involves soldering an impedance matching strip. The field trial encompasses setting up a main station with a File Transfer Protocol (FTP) server on a smartphone, and establishing a connection to it utilizing various antennas over increasing distances through agricultural land. In the past, we have evaluated antennas in a similar manner, and it truly offers an instant insight into their efficiency.
In this particular case, the spiral antenna outperforms a commercial patch antenna and the internal antenna of a laptop with ease, hence making it a highly valuable creation whether you are establishing a stable connection or simply enjoying a bit of casual wireless network exploration.
The resources highlighted here will streamline the creation of spiral antennas, although this is not the first instance where we have discussed this subject.
