Abstract An antenna for transmission of microwave energy, has a plate with openings for receiving energy from a feeding or input waveguide connected to an energy source and for feeding the received energy to a number of antenna or output waveguides provided with one or several openings through which energy from the feeding waveguide is to be emitted. The plate on the input side is provided with tracks in which a part of the feeding waveguide, which part together with the plate forms the feeding waveguide, is fixed, and the plate on the output side is provided with a number of tracks, in each of which a part of an antenna waveguide, which part together with the plate forms the antenna waveguide. In addition both the feeding waveguide part and each antenna waveguide part have the form of an open rectangular container, the edges of which together have the same form as the corresponding tracks of the plate, and the bottom of which is provided with one or several openings.
Antenna apparatus comprising: a plate having input and output sides; a plurality of first tracks cut into the output side of said plate, said first tracks being mutually parallel; a pair of second tracks cut into the output side of said plate, one of said second tracks being connected to first ends of each of said first tracks, and the other end of each of said second tracks being connected to second ends of each of said first tracks whereby a plurality of output-waveguide-wall-accepting means are formed, each having a major axis along a first direction; a pair of third tracks cut into the input side of said plate; a pair of fourth tracks cut into the input side of said plate, one of said fourth tracks being connected to first ends of said third tracks, and the other of said fourth tracks being connected to second ends of said third tracks whereby an input-waveguide-wall-accepting means is formed having a major axis which intersects the major axis of each of the formed output-waveguide-wall-accepting means; and said plate being provided with an opening in the region of each of the major axis intersections.
