Abstract
An active tuned loop-coupled antenna capable of optimizing performance over incremental bandwidths and capable of tuning over a large total bandwidth to be used in wireless communications. The active loop is capable of serving as the radiating element or a radiating element can be coupled to this active loop. Multiple active tuned loops can be coupled together to extend the total bandwidth of the antenna. Active components can be incorporated into the antenna structure to provide yet additional extension of the bandwidth along with increased optimization of antenna performance over the frequency range of the antenna.
