摘要： In a parallel multistage band-pass filter, a transmission line having an electrical length substantially equal to half (λ/2) of the wavelength of the transmission signal is incorporated between the port on the input terminal side of the odd number (2n−1)th resonator numbered from the input terminal side and the port on the input terminal side of the even number (2n)th resonator numbered from the input terminal side; and a transmission line having an electrical length substantially equal to λ/2 is incorporated between the port on the output terminal side of the even number (2n)th resonator numbered from the input terminal side and the port on the output terminal side of the odd number (2n+1)th resonator numbered from the input terminal side. Moreover, a transmission line for adjustment of a transmission phase between the input terminal and the output terminal is incorporated between the first resonator numbered from the output terminal side and the output terminal.

摘要： A transmission line includes a dielectric substrate having first and second principal surfaces. A first conductive layer is provided on the first principal surface. A protrusion is provided on the second principal surface and a second conductive layer is formed so as to cover the outer surface of the protrusion. A slot is formed in the first principal surface such that the slot extends through the first conductive layer and faces the protrusion. Accordingly, a high-frequency signal does not radiate from the second principal surface and locally transmits with low loss between the bottom surface of the protrusion and the slot.
摘要翻译：传输线包括具有第一和第二主表面的电介质基片。第一导电层设置在第一主表面上。在第二主表面上设置突起，形成第二导电层以覆盖突起的外表面。在第一主表面中形成槽，使得狭槽延伸穿过第一导电层并且面向突起。因此，高频信号不会从第二主表面辐射，并且在突起的底表面和槽之间以低损耗局部地传输。

摘要： A projecting part is formed on the bottom surface of a dielectric substrate and a first conductive layer and a second conductive layer are respectively formed on the top surface and the bottom surface of the dielectric substrate. A plurality of through holes are formed along the left and the right of the projecting part. A coplanar line including a center electrode sandwiched between two grooves is provided on the top surface. Two slots connected to the top end of the coplanar line are formed at a position corresponding to the position of the projecting part, whereby a waveguide formed by the projecting part and the coplanar line are interconnected via the slots.
摘要翻译：在电介质基板的底面上形成有突出部，在电介质基板的上表面和下表面分别形成有第一导电层和第二导电层。沿着突出部的左右方向形成有多个贯通孔。包括夹在两个凹槽之间的中心电极的共面线设置在顶表面上。连接到共面线的顶端的两个槽形成在与突出部分的位置对应的位置，由此由突出部分和共面线形成的波导通过狭槽相互连接。
