Abstract
An antenna having a resonant structure, comprises an antenna element () and an adjacent electrode (A) and control means () for changing a resonance frequency of the antenna element. The control means may comprise a conductive membrane (A) spaced from the antenna element. The resonance frequency then is changed by flexing the membrane, conveniently by applying a potential difference between the membrane and an adjacent control electrode.
