Claims

[Scope of utility model registration request]

A plurality of antenna elements are arranged at appropriate intervals in the longitudinal direction on one end of a rectangular printed circuit board in the transverse direction, and a power divider with a triplate structure is installed on the other end of the rectangular printed circuit board over the entire length thereof. A connector that is electrically connected to the power divider via the short circuit plate is fixed to the short circuit plate placed on the power supply side of the power divider, and the entire structure is directly or reinforced, avoiding the placement position of this connector. It is covered with a cover with a material interposed therebetween, and is cylindrical with a bottom, and the outer surface of the bottom part is formed with a hole through which the fixing flange of the connector can pass. In an array antenna that has a bracket fixed to the cover surface and is kept airtight as a whole; a hole for checking airtightness that communicates with a hole provided at the bottom of the bracket to penetrate the cover and reach the shorting plate. An array antenna characterized by having holes formed therein.
