How do I simulate an antenna?

Open this page and use the live Buck Converter 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 an antenna from your own measurements.

A buck converter chops the input at a fast switching frequency; the inductor and capacitor average it to a lower DC output, Vout = D·Vin. Bigger inductors and faster switching shrink the current ripple. Educational tool.

Output voltage5.04 V

Inductor ripple ΔIL0.29 A

Ripple / load29%

Modecontinuous

Governing equation

V_{o u t} = D \cdot V_{in} = 0.42 \cdot 12 V = 5.04 V Δ I_{L} = \frac{( V _{in} - V _{o u t} ) D}{L f _{s w}} = 0.29 A

Reading this result: Vout tracks D·Vin regardless of load; the ripple you see is set by L and switching frequency, not by the output voltage itself.

About this simulation

The full Buck Converter tool models an antenna 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.
