what are these tracks for?

they are tuned circuits. open ended transmission lines. Or a bored

Presumably, we're looking at either side of the board here ? As one set of
squiggles seems to be connected to "sim1" and the other to "sim2" then maybe
it's a small amount of C with the PCB material as the dielectric ? I've seen
that done before. Or as others have said, transmission lines, maybe with the
bit of C to tune them. Or antennas with C ?
