Biquad Yagi Antenna - 2.4 GHz

thingiverse

If you like what you see, consider leaving a tip. This 2.4 GHz biquad yagi is inspired by Andrew McNeil's YouTube channel, which focuses primarily on antenna design and testing. Check out the Biquad Yagi Customizer to create your own custom antenna design. Thanks to Thingiverse user djinc3ption for providing excellent test data in an anechoic chamber. Review the VSWR, frequency response, 3D propagation graphs, and a link to raw test data on his maker page. This antenna design uses solid 14-gauge 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 (all outside dimensions). I added cylinders with closed ends for attaching a solid reflector and/or base station mount. I made a reflector out of thin sheet metal with drilled holes for small screws and a larger hole with a rubber grommet to pass coax cable through. The parasitic elements are spaced 17mm apart, with the reflector spaced 19 mm from the driven element. These dimensions come directly from Andrew's PCB biquad yagi design. I used short flexible coax cable with an SMA connector to connect the antenna to my USB WiFi adapter. Check out the video that inspired this design: Biquad Yagi 2.4GHz and 5.8GHz Upgrade!
