Abstract
A chaff electronic countermeasure device that includes an antenna element positioned on a substrate and in electrical communication with an integrated circuit. The conductive antenna element includes a conductive composition of a conductive polymer and graphene sheets. The device absorbs from a radar source a first radio frequency having a first amplitude. In response to absorbing the first radio frequency, the device reradiates at least a portion of a second radio frequency having a second amplitude toward the radar source, which results in an increased radar cross section of the device as perceived by the radar source. The second amplitude is higher than the first amplitude. The device is configured to be dispersed from a mobile platform. The device is configured to reradiate at least a second radio frequency toward the radar source, thereby resulting in an increased radar cross section of the device as perceived by the radar source.
