A novel next generation self adaptive smart handset antenna

Abstract

In this paper we presented a novel technique of achieving simultaneous dual frequency tuning via a single variable capacitor. This technique will enable a smaller dual band antenna to operate over a pentaband range. It also allows individual bands to be tuned/optimised independently. Together with a control algorithm, the antenna will continuously sense its environment for any loading effects to achieve optimum matching in all conditions via a closed feedback loop.
