First Claim
Patent Images
1. An antenna system for a device having a metal housing, the antenna system comprising:
- an antenna element configured to couple to and excite current on the metal housing;
an antenna tuning module, the antenna tuning module comprising a switch having a plurality of ports, wherein each port connects a different connection point of a plurality of connection points on the metal housing to a ground reference via a transmission line, wherein the antenna tuning module is coupled to one or more processors configured to perform operations, the operations comprising;
determining a tuning state for the device;
configuring the antenna tuning module to couple a different connection point to the ground reference based at least in part on the tuning state for the device.

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 for sources such as body-loading are compensated at adjusting impedance properties of the combination of radiator and metallized cover.
