Embodiment 1
[0030] 1) Structure: The elliptical waveguide load is composed of a flange 1, a waveguide cavity 2, an absorber 3 and a tail cover 4. The cross section of the waveguide cavity 2 is elliptical, and the absorber 3 is a cone. The angle is 5°, and the length of the absorber 3 is taken as 2 times of λ / 2.
[0031] 2) Material: the flange, the waveguide cavity and the tail cover are made of duralumin LY12; the absorber is made of bakelite; the outer surface of the elliptical waveguide load is anodized.
[0032] 3) Dimensions: the ratio of the minor axis to the major axis of the elliptical section of the waveguide cavity 2 is 0.45.
[0033] 4) Assembly: the flange is connected to one end of the waveguide cavity by silver soldering; the conical bottom surface of the absorber is connected to the tail cover through adhesive, and the sticking position should be slightly away from the left side of the center of the tail cover by 5mm; the tail cover after the glue is completed The plate is...
