い効果がある。(Effects of the Invention) Since the present invention is constructed as described above, when an array antenna is mounted on the outer panel of an aircraft, a ship, etc., the antenna structure and the fairing that protects it protrude from the outer panel. It is particularly suitable for moving bodies with pressurized bulkheads, such as passenger aircraft, because it reduces the amount of holes, limits the number of holes drilled in the outer skin, and makes it easy to maintain airtightness and watertightness of the core. This allows a large-area array antenna to be installed without increasing harmful resistance, and has a significant effect in preventing accidents due to a breach in airtightness when the antenna fairing is damaged.
