Abstract
An antenna methodology where a set of antennas are formed that take the shape of a mobile wireless device and can be integrated into the outer housing of the mobile device. Tuning points are integrated into the design to provide the capability to compensate for hand effects and loading while the mobile device and antenna are touched by the user. The body then becomes a part of the antenna and acts as an anchor for the poles within the matching circuit. These antennas are actively tuned based on detection criteria while dynamically tracking system performance. The structure is based on a loaded loop coupled to an isolated magnetic dipole (IMD) element. The loop is actively tuned according to design rules residing in a processor in the mobile device.
