Abstract (en)
A frequency tunable antenna is provided. Specifically, a device is provided that includes: a ground; an antenna feed; a first radiating arm connected to the antenna feed; a second radiating arm capacitively coupled to the first radiating arm; a switch connected to the second radiating arm, the switch having an open position and a closed position; an inductor connected to the switch on one side and the ground on an opposite side, and, a processor in communication with the switch, the processor configured to open and close the switch to tune a resonance frequency of at least the second radiating arm thereby changing a resonant length of the second radiating arm depending on whether the inductor is connected thereto.
