3D Antenna Pattern Visualizer
Rotate the full 3D radiation pattern for standard antenna geometries, then take a θ or φ cut through it to see exactly how the familiar 2D polar and rectangular pattern plots are generated from the 3D shape. Built for teaching how θ (from +Z) and φ (from +X, in the XY-plane) parameterise the far field.

Isotropic radiator — equal power in every direction. Used as the 0 dBi reference for antenna gain.

Radius = normalised field magnitude (linear scale) · brighter surface = higher radiation intensity, dim = near a pattern null · Z is the antenna's electrical axis for wire elements.
Polar Cutθ = 90°
dB rings from 0 to −40 dB · 0° points toward the top of the plot.
Rectangular Cutθ = 90°
Same cut as the polar plot, on a linear angle axis.
