Abstract: Antenna structures and methods of operating the same of a dual-band inverted-F antenna of an electronic device are described. One device includes a single RF feed line coupled to a dual-band inverted-F antenna. The dual-band inverted-F antenna includes a RF feed coupled to the single RF feed line; a ground element; a first arm; a second arm; and a third arm coupled to the ground element. The RF feed is located at a point that is closer to the third arm than a first opening between a distal end of the first arm and the ground element. The second arm is located on an opposite side of the first arm than the ground element, forming a second opening between the second arm and the ground element and a third opening between the second arm and the first arm.

Abstract: Systems, devices, methods, computer-readable media, techniques, and methodologies are disclosed for optimizing radio frequency configuration of a user device for better power management and faster time to first fix. The radio frequency configuration of user devices may be optimized based on user input analysis, machine learning, or crowd sourcing methodologies.
