How do I simulate a phase-locked loop?

Open this page and use the live Antenna Pattern tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a phase-locked loop from your own measurements.

Dipole length (wavelengths)

A dipole radiates most strongly broadside and nulls off its ends. As it grows past one wavelength the main lobe narrows and side lobes appear — trading a wider beam for more directivity. Educational tool.

Governing equation

E (θ) = \frac{cos ( π L cos θ ) - cos ( π L )}{sin θ}, L = 0.50 λ

Reading this result: The half-wave dipole is the sweet spot: a single clean broadside lobe with the classic ~2.15 dBi gain and no side lobes to waste power.

About this simulation

The full Antenna Pattern tool models a phase-locked loop with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
