Kioan's calculator for building a Cantenna , directional waveguide antenna for long-range Wi-Fi

Demonstrates the construction of a 2.4 GHz horn antenna, specifically designed for WiFi applications, with the potential to add several dB of gain. The resource focuses on the critical dimensions and calculations required for proper operation, including _wavelength_ (Lo) and guide wavelength (Lg) based on the operating frequency (Fo) of 2.442 GHz, corresponding to channel 7. The guide provides a table of European WiFi frequencies, ranging from 2.412 GHz to 2.477 GHz, highlighting the specific channel 7 as the design target. It details how the length of the waveguide (Lg) depends on the diameter of the enclosure, offering a practical approach to antenna construction. This project outlines the necessary measurements like Lo/4 at **31 mm** and provides a link to an external calculator for further design specifics. The horn design aims for a 30-degree beamwidth, making it suitable for focused signal transmission or reception.
