ABSTRACT:
An antenna having a plurality of resonant frequencies and comprising a feed point, a ground point and a conductive track that extends from the feed point and returns to the ground point and means for locally increasing the reactance of the antenna track at a first position coincident with a maximum electromagnetic field associated with at least one of the plurality of resonant frequencies.
