Abstract
An embedded antenna system is described for use with metallized enclosures and housings used with wireless communication devices. One or multiple radiators are coupled to a metal cover, with ground points established on the metal cover to improve radiation efficiency and control the frequency response of the antenna system. Dynamic tuning methods are described wherein detuning of the antenna system from sources such as body-loading are compensated by adjusting impedance properties of the combination of radiator and metallized cover.
