Abstract
A phased array antenna includes a substrate, and dipole element arrays extending in concentric rings about 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 a spacing between the dipole element arrays and the ground plane is different between the dipole element arrays having different size dipole antenna elements.
