Pressurized antenna for electronic warfare sensors and jamming equipment

A remote communications device, comprising:

• a transceiver;
• and
• an expandable, terrestrially-based antenna operationally connected to the transceiver,
• wherein the antenna includes
• a sheet of flexible dielectric material having a first side and a second side,
• a flexible conductive ground plane secured to the first side of the flexible dielectric material,
• at least one flexible, planar conductive element secured to the second side of the flexible dielectric material, wherein the flexible dielectric material is shaped and bonded to form a collapsible enclosed volume with the ground plane forming an inner surface of the enclosed volume,
• a propellant enclosed within the enclosed volume, the propellant configured to release a gas when ignited, and
• an igniter configured to ignite the propellant and temporarily expand the enclosed volume to a predetermined shape such that the ground plane, the dielectric material, and the at least one conductive element cooperate to form a resonant electrical circuit.
