I've seen delay lines on tracks - funny zigzag patterns - but these were
in logic analysers, and were designed to keep the tracks from all the
probes the same length.


Yes, I've seen similar things on PC motherboards, where it's important
to keep the tracks between the CPU/memory controller and the memory
slots the same length.

That isn't what the OP photo shows, though. I certainly agree with
those that think it's an antenna of some kind. Figuring out what "SIM1
and "SIM2" mean might be a clue.

If its a multilayer board, there might be unseen tracks or planes between
the top and bottom wiggly traces, connected to the other 3 contact points.
