ABSTRACT:
An antenna includes a substrate, and an array of dipole antenna elements on the substrate. Each dipole antenna element includes a medial feed portion and a pair of legs extending outwardly therefrom. Adjacent legs of adjacent dipole antenna elements include respective spaced apart end portions with impedance coupling therebetween. An impedance matching layer is adjacent a side of the array of dipole antenna elements opposite the substrate. The impedance matching layer includes an array of spaced apart conductive elements.
