Hertzian Dipole Radiation Pattern

The Hertzian (short) dipole radiates with pattern P(θ)∝sin²θ. Far-field electric field magnitude |E_θ|∝sin θ/r. Explore how array configurations and element count shape the beam.

Array type:

Elements N = 1

Spacing d/λ = 0.50

Phase shift δ = 0°

Frequency (anim): 1.0

P(θ) ∝ sin²θ · |AF(θ)|²
AF = Σ exp(i·n·ψ)
ψ = kd·cosθ + δ

Directivity: — dBi
