    Abstract: PROBLEM TO BE SOLVED: To provide a band-pass filter of a reduced size, which ensures a sufficient mechanical strength.
    SOLUTION: The band-pass filter includes; a dielectric block 2 substantially formed into a rectangular prism comprising a first part belonging to a region from one cross section to other cross section of the prism in parallel with the one cross section and second and third parts separated by the first part; and a metalized part formed on the surface of the dielectric block 2, in which the first part configures a cut-off waveguide 11 and the second and third parts respectively configure first and second resonators 12, 13. The metalized part includes inductive electrode pieces 9, 10 formed on the surface of the first part of the dielectric block 2. The inductive electrode pieces 9, 10 formed on the surface of the first part of the dielectric block 2 provide a prescribed coupling coefficient between the first and second resonators 12, 13.

    Abstract: PURPOSE:To obtain about 40dB attenuation at 800MHz and to obtain sufficiently practical trap effect reducing loss at 900MHz+ or -25MHz less than 30dB, by connecting a 1/4 wavelength leading and opening line and capacitive reactance to a transmission line. CONSTITUTION:The 1/4 wavelength leading end opening line 2 of 800MHz is connected to a transmission line 1 of 50OMEGA. A capacity reactance 3 is connected to the same coupling point P. Since the impedance of the line 2 approaches zero at 800MHz, the line 2 is acted as a trap circuit. However, the line 2 is acted as an inductive reactance at the wavelength of frequency higher and close than/ to 800MHz. Therefore, selection of the value of capacitive reactance 3 makes it possible to cancel the inductive reactance and make the reactance approach specific impedance. When the impedance of a transmission line 1 approaches the specific impedance, the loss of insertion can be regarded as approximately zero.

    Abstract translation: 目的：在800MHz时获得约40dB的衰减，并通过将1/4波长的导通线和开路线与电容电抗连接到传输线，获得足够实用的陷波效应，减少900MHz +或-25MHz的损耗，小于30dB。 构成：800MHz的1/4波长的前端开路线2连接到50OMEGA的传输线1。 容量电抗3连接到相同的耦合点P.由于线路2的阻抗在800MHz处接近零，所以线路2用作陷波电路。 然而，线路2在频率高于/高于800MHz的频率的波长处用作感抗。 因此，选择容性电抗3的值可以消除感抗并使电抗接近特定的阻抗。 当传输线1的阻抗接近特定阻抗时，插入损失可以被认为是近似为零。

    Abstract: A substrate is provided to perform a dispersive meta material by using diffraction between electromagnetic waves which pass a plurality of waveguides. A substrate(1) includes a first surface(10), a second surface(20), and a plurality of waveguides(30). An electromagnetic wave is incident on the first surface. The electromagnetic wave is emitted from the second surface. A plurality of waveguides is arranged according to a first axial direction and a second axial direction. The first axial direction is parallel to a polarizing direction of the electromagnetic wave. The second axial direction is vertical to the first axial direction. A plurality of waveguides generates diffraction of the electromagnetic wave by delivering the electromagnetic wave from the first surface to the second surface. A plurality of waveguides generates Fabry-Perot resonance of the electromagnetic wave.
