Systems, devices, and methods for dynamic antenna tuning are provided herein. The method determines an operating mode of a device from first and second modes. The device comprises an antenna having a target impedance that changes based on the operating mode of the device. The method, responsive to determining the operating mode of the device is the first mode, utilizes a first circuit to drive a first impedance of the antenna associated with the first mode to the target impedance to operate the antenna at a predetermined power level in a first frequency bandwidth and a predetermined range. The method, responsive to determining the operating mode of the device is the second mode, utilizes a second circuit to drive a second impedance of the antenna associated with the second mode to the target impedance to operate the antenna at the predetermined power level in the first frequency bandwidth and the predetermined range.
