Abstract
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.
