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。[Detailed description of the invention] Industrial applications 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
〜６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３〜６の共振特性で所定のフィル
タ特性を得るものであった。Conventional technology Conventionally, a signal pattern 2 is provided on a substrate 1 as shown in FIG.
-6 were provided facing each other. Then, a signal is applied to the signal line 2, and predetermined filter characteristics are obtained by the resonance characteristics of the resonance patterns 3 to 6.
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。Problems to be Solved by the Invention However, in the conventional method, the size of the resonant patterns 3 to 5 cannot be increased very much on the limited size substrate 1, so there is a problem that the selectivity Q cannot be increased. Ta.
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 this 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 In order to achieve this object, the present invention provides a groove in the substrate portion between the resonant patterns, and a conductive part connected to each resonant pattern is formed on the inner surface of the groove. This is what I did.
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。If the structure is configured as above, the area of the resonant pattern becomes larger 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はセラミックで作りた基板で
、この基板ｅ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 In FIGS. 1 and 2, reference numeral 6 denotes a substrate made of ceramic, and a signal pattern 7 made of silver metallization is formed linearly on the upper surface of this substrate e.
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８〜１ｏが形成されている。Furthermore, resonance patterns 8 to 1o made of silver metallization are formed opposite to this signal pattern 7.
これらの共振パターン８〜１ｏ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, these resonance patterns 8 to 1o all have a convex shape, and the convex portions of 8 and 10 are directed toward the signal pattern 7, and the convex portions of 9 are directed to the opposite 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
っているのである。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、１
３は共振パターン８に導通され、１４と１６は共振パタ
ーン９に導通され、１６は共振パターン１ｏに導通され
ているのである。そして、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１
７は、第２図のごとく溝１１と１２の内部にも充填され
ているのである。As a result, there are crank-shaped gaps between the resonance patterns 8 and 9 and between the resonance patterns 9 and 10, and this crank part is the second
As shown in the figure, grooves 11 and 12 are formed by cutting out the substrate 6 downward. Conductive parts 13, 14, 15, and 16 are formed on the inner surfaces of these grooves 11, 12, and 1
3 is electrically connected to the resonant pattern 8, 14 and 16 are electrically connected to the resonant pattern 9, and 16 is electrically connected to the resonant pattern 1o. A covering 1 made of synthetic resin also covers these signal patterns 7 and resonance patterns 8 to 10.
7 is also filled inside 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。Effects of the Invention As described above, in the present invention, a groove is provided in the substrate portion between the resonant patterns, and a conductive part that conducts to each resonant pattern is provided on the inner surface of this groove, so that the area of each resonant pattern can be increased. can do.
このため選択度Ｑを高くすることができるのである。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 covering is provided on the substrate as in the embodiment, there is no need to provide a separate shielding case, and since a part of the covering is also filled in the groove, it is difficult to peel off.
