1. An electronic device comprising:
- an antenna including a radiating element having a physical length;
an electrical feed structure connected to the radiating element to supply a drive electrical current to the radiating element; and
a self-tuning element connected to the radiating element that tunes a resonant frequency of the radiating element by creating or removing an electrical short between two points along the physical length of the radiating element, responsive to changes to a physical configuration of the electronic device.

Abstract
An electronic device disclosed herein includes an antenna that self-tunes frequency responsive to changes to a physical configuration of the electronic device to negate a shift in the resonant frequency attributable to the change in physical configuration.

6. An electronic device comprising:
-
an antenna including a radiating element having a physical length; an electrical feed structure connected to the radiating element to supply a drive electrical current to the radiating element; and a self-tuning element fixably connected to the radiating element and configured to create an electrical short between two points along the physical length of the radiating element in a first physical configuration of the electronic device to maintain a resonant frequency of the antenna within a same target frequency band despite a change in device configuration from a second physical configuration to the first physical configuration. - View Dependent Claims (7, 8)
