Abstract
A multi-band antenna including a retractable antenna and a meander antenna wherein the meander antenna may take several forms. In all of the embodiments, the meander antenna comprises first and second meander radiating elements. In one form of the invention, the closed ends of the loops of the second meander radiating element protrude into the open ends of the loops of the first meander radiating element. In other forms of the invention, active and/or passive elements are positioned between the first and second meander radiating elements. In some forms of the invention, the active or passive elements include stubs which protrude into the open ends of the loops of the first meander radiating element.
