Transmitting wideband signals through an electrically small antenna using antenna modulation
MetadataShow full item record
The present invention provides methods and devices to radiate wideband signals. The devices may include a tunable high Q narrowband antenna having a plurality of ports including a feed port and a tuning port as well as a tuning element coupled to the tuning port of the antenna. One or more voltage sources supply energy for radiating a radio frequency signal. A modulating signal generator may also be provided for generating a high data rate signal coupled at the tuning element for modulating the tuning element.
