  • Planar broadband antenna
    Patent number: 8542150
    Abstract: A planar antenna comprising a planarly configured inner radiation element that is surrounded by an outer radiation element, wherein the inner and outer radiation elements each have a feed point. A continuous or discontinuous modification of the distance, which is equal in relation to a symmetrical axis of the inner radiation element, exists between the inner radiation element and the outer radiation element. The distance between the outer and the inner radiation element is different in the area of the two feed points from that in the area facing away from the feed points.
