Abstract
The utility model discloses a smooth transmission multimode resonant cavity, which comprises at least one cavity and a coupled structure capable of exciting two or a plurality of working modes. When an electric field metal is arranged in the cavity, an upper cover plate of the cavity over the electric field metal is also provided with a microwave absorber, the surface or the inner part of which is provided with a microwave absorbing material. When the cavity is not provided with an electric field metal, the microwave absorber is arranged in a place of electric field concentration of certain working mode in the cavity. Through the improvement on the prior art, the smooth transmission multimode resonant cavity overcomes the defects in the prior art and flattens the in-band fluctuation of the multimode resonant cavity, belongs to a filter technology and is mainly used in the electronic systems of various microwave bands, especially in the fields of radar, communications, missile guidance, etc.
