Abstract
An antenna assembly has a conductive line coupled to a feed point. An element is configured to resonate at a predetermined frequency. The element is electrically coupled to the conductive line and aligned perpendicular to the conductive line wherein the predetermined frequency of the element determines a distance from the feed point along the conductive line.
