Abstract

Antennas for a communications device and wireless terminals are provided. A conductive element is provided along with a ground assembly including a ground element coupled to the conductive element. The ground element has a first state and a second state. The first state provides a first resonant frequency band when the ground element is in a first relative position that is a first distance from the conductive element. The second state provides a second frequency band when the ground element is in a second relative position that is a second distance, different from the first distance, from the conductive element.
