高価になる欠点がある。[Problems to be Solved by the Invention] This conventional band-elimination filter has a waveguide line and a cavity resonator integrated, so when it is incorporated into a high frequency section of a microwave band transmitting/receiving device, etc. , it is necessary to add an E-bend waveguide as shown in FIG. 2, or to connect directly to an E-bend waveguide as shown in FIG. Therefore, the shape of the E-curved waveguide becomes larger, especially in the height direction, and
It has the disadvantage of being expensive.
