    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.
