A phased array antenna includes a substrate having a first surface, and a second surface adjacent thereto and defining an edge therebetween. A plurality of dipole antenna elements are on the first surface, and at least a portion of at least one dipole antenna element is on the second surface. Each dipole antenna element includes a medial feed portion and a pair of legs extending outwardly therefrom. Adjacent legs of adjacent dipole antenna elements on the first and second surfaces include respective spaced apart end portions having predetermined shapes and relative positioning for providing increased capacitive coupling between the adjacent dipole antenna elements.

The slot-mode antenna includes an array of slot antenna units carried by a substrate, and each slot antenna unit has a pair of patch antenna elements arranged in laterally spaced apart relation about at least one central feed position. Adjacent patch antenna elements of adjacent slot-mode antenna units include respective spaced apart edge portions defining gaps therebetween, and a capacitive coupling layer or plates overlap the respective spaced apart edge portions to provide increased capacitive coupling therebetween. The capacitive coupling layer may include continuous or periodic capacitive coupling plates along each gap defined by the respective spaced apart edge portions.

A multiband phased array antenna includes a substrate, and dipole element arrays extending outwardly from an imaginary center point on the substrate. Each dipole element array includes dipole antenna elements arranged in an end-to-end relation and having a dipole size different than a dipole size of dipole antenna elements of at least one other dipole element array. A ground plane is adjacent the dipole element arrays and has a different spacing therefrom in an outward direction from the imaginary center point. The different spacing between the ground plane and the dipole element arrays increases from the imaginary center point towards an edge of the substrate.

A phased array antenna includes a substrate, and a patterned conductive layer is on the substrate. The patterned conductive layer defines a plurality of slotted dipole antenna elements each having a medial feed portion associated therewith. Each slotted dipole antenna element includes a pair of slotted legs extending outwardly from the medial feed portion. Pairs of adjacent slotted legs of adjacent slotted dipole antenna elements include respective spaced apart end portions having predetermined shapes and relative positioning to provide increased inductive coupling between the adjacent slotted dipole antenna elements.

A multiband phased array antenna includes a substrate, and dipole element arrays extending outwardly from an imaginary center point on the substrate. Each dipole element array includes dipole antenna elements arranged in end-to-end relation and having a dipole size different than a dipole size of dipole antenna elements of at least one other dipole element array. A ground plane is adjacent the dipole element arrays, and a spacing between the dipole element arrays and the ground plane is different between the dipole element arrays having different size dipole antenna elements. The ground plane has a plateau shape for providing the different spacing between the dipole element arrays.

The dual-polarization, slot-mode antenna includes an array of dual-polarization, slot-mode, antenna units carried by a substrate, with each dual-polarization, slot-mode antenna unit having at least four patch antenna elements arranged in spaced apart relation about a central feed position. Adjacent patch antenna elements of adjacent dual-polarization, slot-mode antenna units include respective spaced apart edge portions having predetermined shapes and relative positioning to provide increased capacitive coupling therebetween. The respective spaced apart edge portions may be continuously or periodically interdigitated to provide the increased capacitive coupling therebetween.

The dual-polarization antenna with a slot pattern can produce vertical polarized energy near the horizon and can scan to near grazing angles. The dual-polarization, slot-mode antenna includes an array of dual-polarization, slot-mode, antenna units carried by a substrate, and each dual-polarization, slot-mode antenna unit having at least four patch antenna elements arranged in spaced apart relation about a central feed position. Adjacent patch antenna elements of adjacent dual-polarization, slot-mode antenna units have respective spaced apart edge portions defining gaps therebetween. Capacitive coupling plates are adjacent the gaps and overlap the respective spaced apart edge portions to provide increased capacitive coupling therebetween.
