MOBILE EQUIPMENT ANTENNA

摘要

A mobile equipment antenna having helical elements capable of providing double-resonance. The inside helical element (42b) is formed by folding back the tip of the outside helical element (42a) and reversely winding it in the outside helical element (42a). Power is supplied from an antenna holder (41) in contact with the lower end of the outside helical element (42a) to a helical antenna part (40) thus formed. Since the inside helical element (42b) is wound in the outside helical element (42a), the helical elements can be double-resonated.
