Abstract: Systems and methods are provided for implementing wideband radiators that conform to regular equilateral triangular lattices with little to no performance compromise for typical offset pairs of dual-polarized element arrangements. This general radiator family/group/configuration can be referred to as the Slant Tri-V (STV) element based on the basic characteristic set of this radiator group and relative differences to conventional array elements normally seen on rectangular or triangular lattice arrangements. The STV array element has wideband, dual-polarized operation and conforms to the most efficiently sampled array lattice for the lowest array element count possible for phased arrays.

Abstract: A phased array antenna including a base plate and a board projecting from the base plate. The board including a dielectric layer and a conductive layer. The conductive layer includes first and second spaced apart radiating elements and a pillar disposed between the first and second spaced apart radiating elements. The pillar is electrically connected to the base plate, and the first and second spaced apart radiating elements are configured to capacitively couple to the pillar.

Abstract: An antenna element including a base plate, a first ground clustered pillar projecting from the base plate, a second ground clustered pillar projecting from the base plate and spaced apart from a first side of the first ground clustered pillar, a first ground member projecting from the base plate between the first ground clustered pillar and the second ground clustered pillar, wherein a distal end of the first ground member is configured to capacitively couple to the second ground clustered pillar, and a first signal member projecting from the base plate between the first ground clustered pillar and the first ground member, wherein the first signal member is electrically insulated from the base plate, the first ground clustered pillar, and the first ground member, and a distal end of the first signal member is configured to capacitively couple to the first ground clustered pillar.
