Abstract: A serially fed front end (FE) network is provided. The serially fed FE network includes a first FE comprising a first FE input/output (IO), a second FE IO, and a first antenna IO coupled to a first antenna element of a plurality of antenna elements. The first FE IO of the first FE is electrically coupled to a particular beamformer (BF) IO of a BF. The serially fed FE network includes a second FE comprising a first FE IO coupled to the second FE IO of the first FE, a second FE IO of the second FE, and a second antenna IO coupled to a second antenna element of the plurality of antenna elements. The BF is communicatively coupled by the serially fed FE network to transmit to and/or receive signals from the first and second antenna elements of the plurality of antenna elements.

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.
