PROBLEM TO BE SOLVED: To obtain a laminated aperture surface array antenna which can be manufactured easily with a general laminating technology for a multi-layered wiring board, is small-sized and thin, and obtains a uniform radiation pattern and excellent antenna characteristics. SOLUTION: This laminated aperture surface array antenna is formed with a dielectric waveguide line 6 composed of a 1st dielectric substrate 1, an upper 1st main conductor layer 2, a lower main conductor layer 3, a through-conductor group 4 for a sidewall, and a through-conductor group 5 for an end surface, multiple spatial resonators 13 each consisting of an upper 2nd main conductor layer 9 having a specific aperture part 10, a through-conductor 11 for a conductor wall formed around the aperture part 10, and a subordinate conductor layer 12 are formed in a transmission direction, and in the upper 1st main conductor layer 2, slots 14 for feeding are formed corresponding to the spatial resonators 13. Consequently, the antenna is small-sized, thin, and simplified in feeding structure and has high efficiency, and a uniform radiation pattern and satisfactory antenna characteristics are obtained. |
