PURPOSE:To obtain a high performance antenna abundant in mass productivity by providing first and second thin film conductors at both surfaces of the dielectric plate, forming plural slender slots at the first thin film conductor and providing the first and second conductive connecting conductors at the side surface on the same side of the slots. CONSTITUTION:On both surfaces of a dielectric plate 21, the first thin film conductor 22 and the second thin film conductor 23 are respectively formed. At an interval D determined beforehand to the first thin film conductor 22, plural slender slots 24 are arranged and formed in the length-wise direction of the dielectric plate 21. The length direction of the slot 24 is approximately coincident with the width direction of the dielectric plate 21. In both side surfaces of the dielectric plate 21, namely, the parallel surface to the arranging direction of the slot 24, the thin film conductors 22 and 23 are mutually connected to conductive connecting conductors 25 and 26. Namely the connecting conductors 22 and 23 are respectively brought into contact with both side surfaces of the dielectric plate 21 and the thin film conductors 22 and 23 are sandwiched from the outer surface and mutually connected by both side end parts. Thus, an antenna can be easily constituted with a printed board.
