Title: Wanted:Ultra tiny bluetooth PCB antenna design (5 x 5mm). Range isnt so critcal
Post by: Psi on November 18, 2017, 10:35:49 am
So im looking for a ultra tiny bluetooth PCB antenna design.
Something that can fit in around a 5mm x 5mm (0.2inch) square.

It can be a fractal antenna or a weird geometry and it really doesn't have to perform amazing.
I wouldnt expect it to, being so small.

Anyone have ideas or known working designs?

Needs to be a PCB antenna, for cost
