Description
【発明の詳細な説明】 産業上の利用分野 本発明は、フィルタ装置に関するものである。Description: FIELD OF THE INVENTION The present invention relates to a filter device.
従来の技術 従来は第３図のごとく基板１上に、信号パターン２を設
け、その信号パターン２に対して複数の共振パターン３
〜５を対向して設けていた。そして信号ライン２に信号
を加え、共振パターン３〜５の共振特性で所定のフィル
タ特性を得るものであった。2. Description of the Related Art Conventionally, as shown in FIG. 3, a signal pattern 2 is provided on a substrate 1, and a plurality of resonance patterns 3 are provided for the signal pattern 2.
~ 5 were provided facing each other. Then, a signal is applied to the signal line 2 to obtain a predetermined filter characteristic with the resonance characteristics of the resonance patterns 3 to 5.
発明が解決しようとする課題 しかしながら従来のものにおいては、限られた大きさの
基板１上において共振パターン３〜５の大きさをあまり
大きくできないので、その選択度Ｑを高くできないとい
う問題点があった。The problem to be solved by the invention However, the conventional one has a problem that the selectivity Q cannot be increased because the size of the resonance patterns 3 to 5 cannot be increased so much on the substrate 1 having a limited size. It was
そこで本発明は、この選択度Ｑを高めることを目的とす
るものである。Therefore, the present invention aims to increase the selectivity Q.
課題を解決するための手段 そしてこの目的を達成するために、本発明は共振パター
ン間の基板部分に溝を設け、この溝の内側面には、それ
ぞれの共振パターンに接続された導電部を形成したもの
である。Means for Solving the Problems To achieve this object, the present invention provides a groove in a substrate portion between resonance patterns, and a conductive portion connected to each resonance pattern is formed on an inner surface of the groove. It was done.
作用 以上の構成とすれば、溝内に形成した導電部の分だけ共
振パターンの面積が大きくなるので、その選択度Ｑを高
めることができるのである。With the above-described structure, the area of the resonance pattern is increased by the amount of the conductive portion formed in the groove, so that the selectivity Q can be increased.
実施例 第１図，第２図において６はセラミックで作った基板
で、この基板６の上面には銀メタライズからなる信号パ
ターン７が直線状に形成されている。Embodiment 1 In FIGS. 1 and 2, 6 is a substrate made of ceramics, and a signal pattern 7 made of silver metallization is linearly formed on the upper surface of the substrate 6.
また、この信号パターン７に対向して銀メタライズから
なる共振パターン８〜10が形成されている。Resonant patterns 8 to 10 made of silver metallization are formed facing the signal pattern 7.
これらの共振パターン８〜10は第１図に示すようにいず
れも凸形状をしており、８と10は凸部を信号パターン７
に向け、９は反対側に向いている。As shown in FIG. 1, all of these resonance patterns 8 to 10 have a convex shape.
9 is facing the other side.
この結果、共振パターン８と９および９と10の間にはク
ランク状の隙間となっており、このクランク部は第２図
のごとく基板６を下方に切り欠いた溝11,12となている
のである。そしてこれらの溝11,12の内側面には、導電
部13,14,15,16が形成され、13は共振パターン８に導通
され、14と15は共振パターン９に導通され、16は共振パ
ターン10に導通されているのである。こして、これらの
信号パターン７と共振パターン８〜10をも覆う合成樹脂
からなる被覆体17は、第２図のごとく溝11と12の部にも
充填されているのである。As a result, there are crank-shaped gaps between the resonance patterns 8 and 9 and 9 and 10, and the crank portions are grooves 11 and 12 formed by notching the substrate 6 downward as shown in FIG. Of. Conductive portions 13, 14, 15, 16 are formed on the inner surfaces of these grooves 11, 12, 13 is conducted to the resonance pattern 8, 14 and 15 are conducted to the resonance pattern 9, and 16 is the resonance pattern. It is conducted to 10. As a result, the cover 17 made of synthetic resin that covers the signal pattern 7 and the resonance patterns 8 to 10 is also filled in the grooves 11 and 12 as shown in FIG.
発明の効果 以上のように本発明は、共振パターン間の基板部分に溝
を設け、この溝の内側面にはそれぞれの共振パターンに
導通する導電部を設けたので、各共振パターンの面積を
大きくすることができる。そのため選択度Ｑを高くする
ことがでるのである。As described above, according to the present invention, since the groove is provided in the substrate portion between the resonance patterns and the conductive portion which is electrically connected to each resonance pattern is provided on the inner side surface of the groove, the area of each resonance pattern is increased. can do. Therefore, the selectivity Q can be increased.
また、実施例のごとく基板上に被覆体を設ければ別途遮
蔽ケースを設ける必要がなく、しかも、その一部が溝内
にも充填されているので剥がれにくいものになるのであ
る。Further, if the cover is provided on the substrate as in the embodiment, it is not necessary to separately provide a shielding case, and part of it is filled in the groove, so that it is difficult to peel off.
