Design your PCB antenna. Match it. Ship it.
LW RF Studio simulates your printed IFA/MIFA/planar antenna on the real board stackup, then builds the matching network with parts you already have on the bench.
One licence. Yours forever. No subscription.

FAQ
Is the free KiCad plugin really free forever?
Yes. LW Antenna Check shows your antenna’s VSWR, unlimited in time. It’s a real tool, not a trial.
What if I buy a new PC?
Deactivate on the old machine, get a new key. Free, instant, as often as you need.
Do I need internet to use it?
A licence is verified locally, so a licensed PC works offline. At start the program contacts our server (see the privacy page) to run the 30-day trial; without internet it still starts.
Student discount?
The Student licence (€149) covers students, academics and hobbyists. Non-commercial use only.
Can I try before buying?
Every PC gets 30 days of the full Professional version on install.
