Abstract
Apparatuses, methods, and systems for an antenna element are disclosed. For an embodiment, the antenna element includes a feed line layer, a first substrate adjacent to the feed line layer, a ground layer adjacent to the first substrate, a second substrate adjacent to the ground layer, and a third layer adjacent to the second substrate. The feed line layer includes a conductive fork-shape that includes a conductive handle adapted to be electrically connected to a center conductor of a coaxial line, a conductive cross-section that crosses an end portion of the conductive handle, and a plurality of conductive fingers. For an embodiment, a rectangular slot is formed in the ground layer, wherein a length of the rectangular slot is perpendicular to the conductive handle. For an embodiment, the third layer includes four parasitic elements, wherein each parasitic element is electrically connected to the ground layer through a shorting via.
