イアンテナ。 A power divider with a triplate structure in which a plurality of antenna elements are arranged on one end of a rectangular printed circuit board in the transverse direction at appropriate intervals in the longitudinal direction, and the other end of the rectangular printed circuit board is arranged over the entire length of the board in the longitudinal direction. A plurality of column arrays are arranged at appropriate intervals so that the printed circuit board faces face each other, and the column array is formed by connecting a plurality of antenna elements and a power divider with a feed line, and the entire column array is covered with a cover. In an array antenna in which a metal conductor rod serving as a reflector is placed on the side of a power divider between column arrays and at a position about 1/4 wavelength behind the antenna element;
An array antenna characterized in that the length of the feed line is shorter than the distance between the antenna element and the metal conductor bar.
