PROBLEM TO BE SOLVED: To provide a planar array antenna with an easy reduction of a thickness dimension.SOLUTION: The planar array antenna includes: a first dielectric plate 103; a plurality of radiation elements 101 arranged on one surface of the first dielectric plate 103; and a first electric conductor 105 having a plurality of slots 113 formed on another side of the first dielectric plate 103 and corresponding to the plurality of radiation elements 101. The planar-array antenna which includes A plurality of post wall waveguides (each post wall waveguide is a portion prescribed by a conductor post set 111) corresponding to the plurality of radiation elements 101 is installed on the first electric conductor 105. Each post wall waveguide can supply power to corresponding one radiation element 101 through corresponding one slot 113.SELECTED DRAWING: Figure 4 |
