NOVELTY - The assembly (12) has a first active tuning element adapted to vary a current mode about a first parasitic element for actively steering a radiation pattern associated with a first antenna element. A second parasitic element is positioned within an antenna volume. A second active tuning element is associated with the second parasitic element and adapted to vary a reactive coupling between the first antenna element and the second parasitic element for actively tuning a frequency characteristic associated with the first antenna element.    USE - Modal antenna integrated battery assembly for a portable electronic device such as cellular phones, personal media devices and laptops.    ADVANTAGE - The assembly provides an improved antenna for enhanced performance of a related device by operating at FM and DVB-H frequencies without adding bulk space to the associated device. The antenna utilizes various characteristics of a battery assembly for loading effects of the antenna, thus improving antenna characteristics and performance. The assembly can provide an enhanced antenna system which successfully enables efficient operation over the FM and DVB-H frequencies while providing component volume integration within strict design requirements of portable wireless devices, where the antenna system is effectively operated without interference with a main antenna or wireless components of the portable wireless device. The layers are fixed on an outer cover of the battery assembly, where each layer includes multiple portions of the antenna, thus providing a multi-layer antenna assembly. The components are incorporated into antenna structures to provide extension of bandwidth along with increased optimization of antenna performance over frequency range of the antenna. The assembly designs antenna feed and ground connections into a battery, where the connections are located to battery terminals for efficient manufacturing of the antenna-battery assembly.    DETAILED DESCRIPTION - The first antenna element is selected from a group consisting of a planar conductor, coil, monopole, dipole and inverted F antenna (IFA), a microstrip antenna, a single resonance isolated magnetic dipole (IMD) antenna, a dual resonance IMD antenna, a planar IMD antenna and a wire. The active tuning elements are a varactor diode, a tunable capacitor and a switched capacitor network. An INDEPENDENT CLAIM is also included for a method for reusing space of a portable electronic device to form a modal antenna.
