Abstract

Apparatus comprising first and second planar tapered slot antenna elements arranged substantially perpendicularly to each other, at least one of the first and second planar antenna elements including a slot serving to interlock the first and second antenna elements in the substantially perpendicular arrangement, and at least one metallic strip on one side of the first planar antenna element located in the region of interlocking. Other features of the antenna elements are also discussed.
