Summary:A radiator element for RF communications formed of a planar conductive material positioned upon a planar dielectric substrate surface. Two lobes formed of the conductive material have side edges abutting a cavity decreasing in cross section between the lobes. The cavity has a widest point configured to receive RF frequencies at the lowest frequency and a narrowest point configured to receive a highest frequency of the element. Opposing pairs of notches in the side edges of the lobes along the decreasing edges of the cavity enhance the frequency of operation for frequencies paired to the distance between the pairs of notches.
