Abstract
In a printed antenna, a window is formed in a grounded conductor provided on one side of an insulator substrate, and a strip conductor is formed in the window as a strip antenna element. The grounded conductor has convex portions projecting toward a central portion of the strip conductor in a longitudinal direction of the strip conductor. Furthermore, in a printed antenna, a window is formed in a grounded conductor provided on one side of an insulator substrate and two strip conductor are formed in the window and a short conductor is provided to connect a longitudinally central portion of each of the strip conductor with the grounded conductor. Furthermore, in a printed antenna, a window is formed in a grounded conductor provided on one side of an insulator substrate, a strip conductor is formed in the window and a short antenna element is formed in the grounded conductor. A short conductor connects a longitudinally central portion of the strip conductor with the grounded conductor. Furthermore, a reflector plate may be provided or a plurality of the above-mentioned printed antenna are arranged on an insulator conductor.
