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.

Abstract: A phased array antenna comprising a plurality of antenna modules, each antenna module comprising a radiating element made of an electrically conductive material printed on a fabric substrate by a screen-printing process and/or an inkjet printing process; and, a signal input port comprising at least one probe electrically coupled to said radiating element, said probe being configured to be coupled to a corresponding transceiver module so that an amplitude and phase of each of said radiating elements can be independently controlled. Further, a method for manufacturing the phased array antenna, comprising: printing an electrically conductive material on a fabric substrate by a screen-printing process and/or an inkjet printing process, so as to form said radiating element for each of the antenna modules; and for each of the antenna modules, electrically coupling said radiating element to said signal input port, thereby assembling the plurality of antenna modules.
