Abstract
An antenna system that permits the size of the ground plane to be reduced while mitigating the negative performance impacts normally associated with sub-optimal ground plane size. The antenna system comprises a ground plane, a radiating element and an isolated conductive structure for electromagnetically enclosing the radiating element. A first current on the radiating element induces a second current on the ground plane proximate the isolated conductive structure thereby inducing a third current on the isolated conductive structure opposing the second current wherein the third current creates an electromagnetic field.
