Abstract: Structures and configurations for planar ultrawideband modular antenna arrays. One example of a PUMA array includes an unbalanced RF interface, a lattice of horizontal dipole segments directly fed with the unbalanced RF interface, the lattice being arranged in either a dual-offset dual-polarized configuration or a single-polarization configuration, and a metallic plate capacitively-coupled to the lattice of horizontal dipole segments and pinned to a ground plane with a first plated via.

Abstract: Various aspect and embodiments of a modular wideband antenna element are disclosed. The antenna element includes a support structure comprising a feed network and first and second arbitrarily-shaped radiator elements extending along a main axis of the antenna elements. Each of the first and second arbitrarily-shaped radiator elements comprises disconnected radiator body components separated by gap regions. Each arbitrarily-shaped radiator elements has a wider end and a tapering free end to provide a tapered slot region. The wider ends of the first and second arbitrarily-shaped radiator elements are located closer to the support structure. The tapering free ends of first and second arbitrarily-shaped radiator elements are located farther from the support structure. The first and second arbitrarily-shaped radiator elements are configured to be electrically coupled to the feed network.

Abstract: A modular wideband antenna element for connection to a feed network. There is a ground plane, and first and second flared fins above the ground plane. The fins each define a connection location that is relatively close to the ground plane and tapering to a free end located farther from the ground plane. The connection location of the first fin is electrically coupled to the feed network and the connection location of the second fin is electrically coupled to the ground plane. There are one or more additional first traces electrically connecting the first fin to the ground plane and one or more additional second traces electrically connecting the second fin to the ground plane.

Abstract: A planar ultrawideband modular antenna for connection to a feed network. The antenna has a ground plane, and an array of antenna elements spaced from the ground plane, each antenna element comprising a pair of arms. A first fed arm is electrically coupled to the feed network. The grounded arm is directly electrically coupled to the ground plane. There are one or more conductors such as conductive vias electrically connecting the fed arm to the ground plane, and optionally there are one or more additional conductors electrically connecting the grounded arm to the ground plane.
