Abstract
A slotted leaky waveguide array antenna comprises a flat, thin bottom plate made of a metallic material; a flat, thin slotted plate made of a metallic material, and disposed parallel with the bottom plate at a predetermined distance from the bottom plate to form a space between the slotted plate and the bottom plate, the slotted plate being formed with a plurality of slots arranged in substantially parallel rows extending in a predetermined guide axial direction; a plurality of flat, thin side walls made of a metallic material and arranged in the space so as to partition the space between the bottom plate and the slotted plate into a plurality of waveguides communicating with each other and including radiation waveguides extending in parallel in the guide axial direction, a lower surface of each of the side walls being fixed to the bottom plate and an upper surface thereof being fixed to the slotted plate; and an electrically conductive adhesive agent layer between the upper surface of each of the side walls and the slotted plate for fixing them to each other.
