Abstract: An antenna system can include a first panel of radiators that extend from a vertex in a first substantially linear direction. The antenna system can also include a second panel of radiators extending from the vertex in a second substantially linear direction. The first panel of radiators and the second panel of radiators form an angle between about 1 degree and about 45 degrees to enhance gain.

Abstract: According to one embodiment of the invention, an end-fire cavity slot antenna array structure includes an upper skin formed from a composite material corresponding to a outer surface of an aircraft wing a lower skin formed from a composite material corresponding to a portion of an inner surface of the aircraft wing and a plurality of proximately positioned electrically conductive elements disposed between the upper and lower skins. Each electrically conductive element is formed from at least one sheet of composite material having an electrically conductive surface, and the sheet of composite material is configured such that the electrically conductive surface defines an inside surface of the electrically conductive element and any outside surfaces of the electrically conductive element that are in contact with an adjacent electrically conductive element.
