Abstract
An end-fire tapered slot antenna is described. The antenna includes a conductive ground plane having a pass-through opening recessed therein, and a dual tapered slot element (DTSE) passing through the pass-through opening. The DTSE includes a substrate, a radiating portion including a first and second pairs of radiating wings symmetrically arranged on the opposite sides of the substrate, and a base portion electrically coupled to the radiating portion and including first and second pairs of the legs passing through the pass-through opening of the conductive ground plane. The legs inner edges define a slot line on each side of the substrate having a tapered shape with increasing a distance between the inner edges. Vias elements are arranged along an entire perimeter of the radiating wings electrically connecting the radiating wings and the legs arranged on the opposite sides of the substrate. Electrical shunts are located on each side of the substrate for connecting the radiating wings of the DTSE to the conductive ground plane.
