Abstract
A first printed circuit board for vertical polarized wave has a plurality of vertical polarized wave elements which serves as antenna elements, and a first feeder circuit which is connected to the plurality of vertical polarized wave elements. A second printed circuit board for horizontal polarized wave has a second feeder circuit which is connected to a plurality of horizontal polarized wave elements which serves as antenna elements, and is mounted with the plurality of horizontal polarized wave elements. A cutout portion is provided between the adjacent two vertical polarized wave elements of the first printed circuit board, and the first and second printed circuit boards are arranged parallel so that the horizontal polarized wave elements are arranged in the cutout portions of the first printed circuit board. A reflecting plate has a concave section extending to one direction, and the plurality of vertical polarized wave elements and the plurality of horizontal polarized wave elements are arranged alternately in one direction inside the concave section.
