I have rarely seen such good antenna matching. We designed two parts between which we can put our foil antenna made from 0.1 mm copper foil. I tried to keep the permittivity of the PLA material as low as possible in order to minimize the influence on the antenna's electro-magnetic properties.

You could print without a top layer. This would allow for zero infill needed, so you’d be left with just bottom and walls.

Yes, that would be even better! Thanks for your comment.
Admirable experiments on a 3D printed antenna, but why won't a PCB version, be both easier and cheaper?

Thanks for your comment. That is a very good point! And I am on the way to come up with a PCB version together with an updated dimensioning tool. So, stay tuned! Happy holidays and best regards. Klaus

I suppose it's because testing PCB version takes a bit more time.

Exactly! Especially when you have make changes. But anyway, my goal is a PCB vesion.
