The application discloses a miniaturized three-passband filter of a substrate integrated waveguide built-in stripline resonator, which is composed of two SIW resonators, two one-end short-circuit and the other-end open-circuit lambda / 4 stripline resonators and two two-end open-circuit lambda / 2 stripline resonators, and the resonators form a three-passband filter in a series topology structure. The application utilizes the TE101 mode of the two SIW resonators, firstly, two one-end short-circuit and the other-end open-circuit lambda / 4 stripline resonators are symmetrically placed in the two SIW resonators to form a two-stage point and double-passband filter, and on the basis, the two one-end short-circuit and the other-end open-circuit lambda / 4 stripline resonators are coupled with the two two-end open-circuit lambda / 2 stripline resonators to form a two-stage point and three-passband filter. By embedding four stripline resonators in the SIW cavity, the miniaturization of the overall structure is realized, and the circuit area can be significantly reduced by about two-thirds while the number and order of passbands are maintained.
