PHASED ARRAY ANTENNA WITH AN IMPEDANCE MATCHING LAYER AND ASSOCIATED METHODS

摘要

An antenna (10) includes a substrate (68), and an array of dipole antenna elements (70) on the substrate. Each dipole antenna element (70) includes a medial feed portion (72) and a pair of legs (74) extending outwardly therefrom. Adjacent legs of adjacent dipole antenna elements (70) include respective spaced apart end portions (76) with impedance coupling therebetween. An impedance matching layer (24) is adjacent a side of the array of dipole antenna elements (70) opposite the substrate (68). The impedance matching layer (24) includes an array of spaced apart conductive elements (30).
