Zusammenfassung: | The invention discloses a high-frequency selective band-pass filter based on 1/8 mode substrate integrated waveguide. The high-frequency selective band-pass filter comprises an upper layer medium substrate and a lower layer medium substrate, wherein the upper layer medium substrate is provided with an upper metal layer; the lower layer medium substrate is provided with a lower metal layer; a middle metal layer is arranged between the upper layer medium substrate and the lower layer medium substrate; two sections of metallization through holes are formed in the upper layer medium substrate; two end metallization through holes are formed in corresponding positions of the lower layer medium substrate; the upper and lower metal layers are both in isosceles right triangle shapes; one feed microstrip line is connected with the upper metal layer in a position, near the end point, of the inclined edge of the upper metal layer; the other feed microstrip line is connected with the lower metal layer in a corresponding p |
