Patent ID: 7369081

Claim:
A chaff element for interfering with radar signals when the chaff element is deployed in an airspace, the chaff element comprising: a. a dielectric substrate; b. a pair of elongate electrically conductive elements disposed on said dielectric substrate, said pair of elongate electrically conductive elements having a total length of approximately one-half wavelength for a radio frequency associated with the radar signals; c. a switch arranged to electrically couple the pair of elongate electrically conductive elements together, the switch opening and dosing responsive to a control signal, the switch being mounted on said dielectric substrate and adjacent said pair of elongate electrically conductive elements; d. an oscillator circuit for generating said control signal, the oscillator circuit being mounted on said dielectric substrate; e. a battery for energizing the oscillator circuit, the battery being mounted on said dielectric substrate; and f. charging connections mounted in the dielectric substrate and electrically connected to the battery, wherein the charging connections are adapted to permit the battery to be joined to an outside power source in order to charge the battery.
