    • A line width on the grounded side of distributed-constant-line-type resonators which form a distributed-constant-line-type filter is made wider than a line width on the open side. By increasing the line width on the grounded side, where a larger electric current flows, of a distributed-constant-line-type resonator, the line resistance of the distributed-constant line decreases, making it possible to reduce the loss of the distributed-constant-line-type resonator and further to reduce the insertion loss of the distributed-constant-line-type filter. Further, by decreasing the line width on the open side to less than the line width on the grounded side, an increase in the size of the filter because the line width on the grounded side is increased can be prevented.
    • 形成分布式恒定线型滤波器的分布式恒定线型谐振器的接地侧的线宽比开放侧的线宽宽。 通过增加分布常数线型谐振器的电流流过的接地侧的线路宽度,分布常数线路的线路电阻减小,能够减少分布式线路型谐振器的分布式线路型谐振器的损耗, 并且进一步减小分布式恒定线型滤波器的插入损耗。 此外,通过将开路侧的线宽度减小到接地侧的线宽,能够防止由于接地侧的线宽增加而导致的滤波器尺寸的增大。

    • The invention provides a high frequency filter which can facilitate filter-characteristic adjustments and miniaturization and can obtain an excellent broadband characteristic. In addition, the invention provides a filter device using the high frequency filter, and an electronic apparatus incorporating the same. In this filter, a ground electrode is arranged on one of the main surfaces of a dielectric substrate. On the other main surface thereof there are arranged two or more microstrip lines, and one end of each microstrip line is grounded via a through-hole to form a high frequency filter. The microstrip lines and the shared through-hole constitute microstrip line resonators, which are coupled via the inductance of the through-hole. With this arrangement, there is no need for an additional coupling element. Thus, the size of the high frequency filter can be reduced. Furthermore, since a large coupling coefficient can be obtained, the high frequency filter can have a broadband characteristic.
    • 本发明提供一种可以促进滤波器特性调整和小型化的高频滤波器,并且可以获得优异的宽带特性。 此外,本发明提供一种使用高频滤波器的滤波器装置,以及包含该滤波器的电子装置。 在该滤波器中,在电介质基板的一个主面上配置接地电极。 在另一个主表面上布置有两条或多条微带线,每条微带线的一端通过通孔接地,形成高频滤波器。 微带线和共享通孔构成微带线谐振器,其通过通孔的电感耦合。 通过这种布置,不需要额外的耦合元件。 因此,可以降低高频滤波器的尺寸。 此外,由于可以获得大的耦合系数,所以高频滤波器可以具有宽带特性。

    • A bandpass filter is capable of forming attenuation extremes on both sides of a passband. Multiple microstrip line resonators, one end of each being an open terminal and the other end connecting to a ground electrode, are provided in a row, and the inner microstrip line resonators are bent in a C-shape so that the open terminals of the outer microstrip line resonators project further than the inner microstrip line resonators. The line of sight between the open terminals of the microstrip line resonators is improved and capacitance is formed there, so that attenuation extremes can be formed on both sides of the passband, and the amount of attenuation can be increased.
    • 带通滤波器能够在通带两侧形成极限衰减。 多个微带线谐振器,其一端是开放端子,另一端连接到接地电极,并列设置为内部微带线谐振器,使得内部微带线谐振器弯曲成C形,使外部的开放端子 微带线谐振器比内部微带线谐振器更突出。 微带线谐振器的开路端子之间的视线被改善,并且在那里形成电容,从而可以在通带的两侧形成衰减​​极限,并且可以增加衰减量。
