気長のその変化量を△Θcとする。In this communication device, since a waveguide type filter having a linear structure is used, it often hinders the miniaturization of the device. Further, in order to miniaturize the device, a plurality of susceptance elements are arranged in the above-mentioned linear waveguide filter, and the E-plane or H-plane is bent at a predetermined position of the susceptance element. Although it is possible to use, it is not possible to obtain a desired electric length and thus a desired performance by simply making a curved structure. 2 (a) is an equivalent circuit of a waveguide type filter having a linear structure, and FIG. 2 (b) is an E plane at the position of the i-th susceptance element for the linear structure of FIG. 2 (a). Or, an equivalent circuit of a waveguide filter having an H-plane curved structure is shown. In the figure, jB i is the susceptance of the i-th susceptance element, and θ i-1 and θ i are the optimum electrical lengths for obtaining the desired characteristics between the susceptances. Due to the curved structure, the equivalent susceptance jB c is generated, the electric length between the susceptances is changed, and desired characteristics cannot be obtained. Let ΔΘ c be the amount of change in electrical length.
