Abstract
A conforming dismount antenna for use in a communication system includes a signal converter, a modulation component, a flexible fiber optic cable, and a flexible radiating element. The flexible fiber optic cable connects the conforming dismount antenna to a radio transceiver. The conforming dismount antenna bends to the contours of the user wearing the conforming dismount antenna or conforming to the contours of camouflage netting resting on a vehicle. When transmitting or receiving a broadcast, the conforming dismount antenna converts the radio frequency signal into a digital optical signal within the conforming dismount antenna. Communication systems including the conforming dismount antenna and methods of using the conforming dismount antenna are also described.
Claims20
A communication device comprising:
