Abstract
The present disclosure generally relates to any device capable of wireless communication, such as a mobile telephone or wearable device, having one or more antennas. The antenna has a structure with multiple resonances to cover all commercial wireless communications bands from a single antenna with one feed connection to the main radio system. The antenna is usable where there are two highly efficient, closely spaced resonances in the lower part of the frequency band. One of those resonances can be adjusted in real time by using a variable reactance attached to the radiator while the other resonance is fixed.
