Abstract
A first value of an operational center frequency of a signal to transmit is determined according to received user input. The operational center frequency is centered within a first band of frequencies and the first band of frequencies has a first bandwidth. A single loop antenna is tuned to match the first value of the center frequency and the single loop antenna is arranged and configured to operate across a second band of frequencies having a second bandwidth. The first bandwidth is less than the second bandwidth. The signal is transmitted from the single loop antenna according to the first value of the operational center frequency to provide a transmitted signal.
