Abstract
A modal antenna is formed within a battery assembly for use with a portable electronic device. In certain embodiments, the antenna is printed on an exterior surface of a battery enclosure using a conductive ink. In other embodiments, the antenna is attached, or etched, on a substrate; the substrate may at least partially include a battery housing. The antenna can include an Isolated Magnetic Dipole (IMD) antenna, or other radiating structure. Active components, such as active tuning components, are optionally included in the antenna-integrated battery assembly for the purpose of tuning the antenna.
Claims14
A modal-antenna integrated battery assembly, comprising:
- a battery assembly having an inner portion enclosed within a battery housing, said inner portion including an anode, cathode, and a separator positioned therebetween;
- and
- a modal antenna integrated within said battery assembly, said modal antenna comprising:
- a first antenna element positioned above a ground plane and forming an antenna volume therebetween;
- a first parasitic element positioned outside of said antenna volume and adjacent to said first antenna;
- a first active tuning element associated with said first parasitic element, said first active tuning element adapted to vary a current mode about said first parasitic element for actively steering a radiation pattern associated with said first antenna element;
- a second parasitic element positioned within said antenna volume;
- and
- a second active tuning element associated with said second parasitic element;
- said second active tuning element adapted to vary a reactive coupling between said first antenna element and said second parasitic element for actively tuning a frequency characteristic associated with said first antenna element;
- wherein each of the first and second parasitic elements are configured to be adjusted using the corresponding first and second tuning elements for actively changing a radiation pattern characteristic associated with the antenna.
