1. An antenna arrangement comprising:
a substrate;
a ground plane;
a driving element proximate to the substrate and electrically connected to the ground plane, the driving element including a feed point for receiving an input current signal;
a first parasitic element electrically connected to the driving element;
a second parasitic element longer than the first parasitic element and electrically connected to the driving element;
a third parasitic element shorter than the second parasitic element and electrically connected to the second parasitic element; and
a fourth parasitic element shorter than the third parasitic element and electrically separated from the first, second and third parasitic elements.
