1. A transceiver, comprising:
- a mufti-layer printed circuit board comprising;
a layer that serves as a first ground plane; and
an antenna for transmitting and receiving radio signals;
a communication module housing said mufti-layer printed circuit board;
a second ground plane;
a removable jacket for said communication module, housing said second ground plane; and
at least one ground contact for connecting said first ground plane and said second ground plane,wherein said first ground plane is too short for said antenna to resonate at a desired frequency, but said first and second ground planes, when connected, provide a combined ground plane sufficient for said antenna to resonate at the desired frequency.
