Abstract: An antenna element (100) comprises an active patch formed by a conductive layer (104) on a front surface of a substrate (102) and a parasitic ground patch (106) on a back surface of the substrate. The active patch has a spiral slot (112) in a central portion, and peripheral portions (110a-110d) which are substantially wider than the spiral slot. A signal feed strip (114) extends from a side of said active patch across the front surface of the substrate. Two signal ground strips (116, 118) are provided on the front surface, each separated from the active patch by a predetermined gap (120, 122). The parasitic ground patch has a slot in a central portion substantially back-to-back with the central portion of the active patch through the substrate. The element has broadband properties that can be tuned by various modifications. Several elements can be used in close array, with lower cross-talk than known antenna designs.
