Abstract
A multielement planar antenna has a substrate, a plurality of antenna element pairs disposed on a first main surface of said substrate, each of the antenna element pairs including first and second antenna elements each made of a circuit conductor, a metal conductor disposed on a second main surface of the substrate, and a slot line defined in the metal conductor. Each of the antenna element pairs has a microstrip line interconnecting the first and second antenna elements. The slot line crosses the microstrip lines and is electromagnetically coupled to the microstrip lines for feeding the first and second antenna elements. The slot line is fed at its central area by a microstrip line or a coplanar line.
