Abstract:
1. A removable jacket for a modular communicator, comprising: a connector for connecting the jacket to a modular communicator that comprises an antenna and a ground plane for the antenna, wherein the jacket may be attached to and detached from the communicator; an extended ground plane for the antenna, housed within the jacket; and two ground contacts separated by a gap that is less than 15 mm, for connecting said extended ground plane to the ground plane of the communicator, each ground contact having a length of approximately 6 mm and a width of 2-4 mm, wherein the ground plane of the communicator is too short for the antenna to resonate at a desired frequency, but the ground plane of the communicator when connected with said extended ground plane, provides a combined ground plane sufficient for the antenna to resonate at the desired frequency.
