PROBLEM TO BE SOLVED: To provide a small and lightweight superwideband printed antenna at a low cost. SOLUTION: In a printed antenna comprising a dielectric substrate and a set of antenna elements arranged on the substrate, the antenna elements are arranged independently and contiguously to the substrate. When xy coordinates having an origin between the antennas is defined on the plane arranged with respective antenna elements and each antenna element is arranged in the x-axis direction, each antenna element is shaped such that the length in the y-axis direction perpendicular to the x-axis increases as it recedes outward in the x-axis direction from the central part of the substrate, and an impedance matching part is provided integrally with each antenna on the feeder side thereof.
