What this tool is for
Calculate BiQuad antenna element length for WiFi, 2.4 GHz and RF projects.
Basic formula
BiQuad side length ≈ wavelength / 4.
Design notes
Use these values as a starting point. Real RF performance depends on PCB layout, ground plane, enclosure, cable loss, connectors and measurement conditions.
Common mistakes
Common mistakes include ignoring coax loss, poor antenna placement, missing ground plane, wrong impedance and testing too close to objects.
