PURPOSE:To simplify the constitution by constituting the titled antenna of a parallel line pattern and a vertical pattern arrayed in its one end, coupling both the patterns by a coupling line being parallel to the parallel pattern, and forming it so as to surround an internal area by a pattern of an external area. CONSTITUTION:A pattern, and a conductor pattern 4 are formed on a dielectric plate 6, and an intermediate plate 6, respectively, and the conductor pattern is constituted of two patterns of an internal area 3 and an external area 5. As for the conductor pattern of the internal area 3, a parallel line pattern 20 is arrayed as (a), (b)-(h), a transmission line vertical pattern 22 arrayed in its one end is arrayed as (i), (j)-(o), both the patterns are allowed to conduct by (p), (q)-(u) of a coupling line 24 being parallel to the pattern 20, and a current is focused by a focusing end 26. It will suffice that width of the pattern 20 is H, its length is L, and the number of pieces is 2<n>, a pitch P is an equal interval, and with respect to wavelength lambda of a receiving radio wave, L=lambda/4, (2<n>-1)=lambda/2. In case a horizontal polarized wave is made incident vertically on the antenna plane, a current generated in each parallel pattern element is combined in a tournament shape, and becomes a large current. According to this constitution, a conductive reverse side plate becomes unnecessary.
