Biquad Yagi Antenna - 2.4 GHz by ReallyBigTeeth

If you like what you see here, consider leaving a tip.
This 2.4 GHz biquad yagi is Inspired by Andrew McNeil's YouTube channel dedicated primarily to antenna design and testing.
Check out the Biquad Yagi Customizer to create an antenna of your own design.
Thanks to Thingerverse user djinc3ption, there is some excellent test data done in an anechoic chamber. Check out the VSWR, Frequency Responce, and 3D propagation graphs, and a link to the raw test data on his make page.
This antenna design uses solid 14 gauge (~1.7mm) copper wire. The 27mm element is the first parasitic element followed by 28mm, 29mm, 30mm, then the 31.5mm driven element and a 34mm reflector at the rear (these are all outside dimensions). I have added cylinders with a closed end for attaching a solid reflector and/or base station mount. I made a reflector out of a piece of thin 56 mm x 110 mm sheet metal with drilled holes for small screws and a larger hole with a rubber grommet to pass the coax cable through. The parasitic elements are spaced 17mm apart with the reflector spaced 19 mm from the driven element. These dimensions are taken directly from Andrew's PCB biquad yagi design. I used a short length of flexible coax cable with an SMA connector to connect the antenna to my USB WiFi adaptor.
Have a look at the video that inspired this design here: Biquad Yagi 2 4GHz and 5 8GHz Upgrade!
