loop antenna (some on a pcb can look strange - not a loop, but really are)

A small transceiver in a wireless security system uses a small square
spiral
solid wire (3 turns?) as an antenna. The frequency is 315 MHz, I think.

What kind of antenna is this? What are its characteristics?

Web references to peruse?

Just curious...

Thanks,

ask a question here if I hadn't done that already.
