本発明は、例えばミリ波集積回路等に好適なＮＲＤガイ
ド（非放射性誘電体線路）に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an NRD guide (non-radiative dielectric line) suitable for, for example, millimeter wave integrated circuits.
災朱旦技歪
従来のＮＲＤガイドは、第２図に示すように、半波長以
下の間隔をあけて平行になした２枚の金属板１２．１２
の間に、テフロン樹脂等からなる狭幅の棒状をした誘電
体部材１１が挟まれた構造となっている。As shown in Figure 2, the conventional NRD guide consists of two parallel metal plates with an interval of less than half a wavelength.
A narrow rod-shaped dielectric member 11 made of Teflon resin or the like is sandwiched between them.
かかる構造とするのは次の理由に依る。即ち、２枚の金
属板の間隔を半波長以下に小さくすれば、金属板に平行
に偏波した電磁波が遮断されて伝播せず、この状態にあ
るときに誘電体部材を挿入すると、誘電体中では波長が
短縮されて遮断状態が解消され、誘電体部材に沿ってｔ
磁波を伝播させ得るからである。The reason for adopting this structure is as follows. In other words, if the distance between two metal plates is reduced to less than half a wavelength, electromagnetic waves polarized parallel to the metal plates will be blocked and will not propagate.If a dielectric member is inserted in this state, the dielectric Inside, the wavelength is shortened and the blocking state is eliminated, and t
This is because magnetic waves can be propagated.

しかしながら、上述したようなテフロン樹脂等の誘電体
材料は、一般に接着を行い難いため、誘電体部材を金属
板にしっかりと固定する有効な手段がないので、振動や
衝撃を受けると誘電体部材が剥離し伝播モードが変わる
という問題があった。However, dielectric materials such as Teflon resin as mentioned above are generally difficult to bond, and there is no effective means of firmly fixing the dielectric member to a metal plate, so it is susceptible to vibration and shock. There was a problem that the dielectric member peeled off and the propagation mode changed.
本発明はかかる課題を解決すべくなされたものであり、
振動や衝撃を受けても金属部と誘電体部材の間が剥離し
にくく、伝播モードに変化が生じない構成としたＮＲＤ
ガイドを提供することを目的とする。The present invention has been made to solve such problems,
NRD has a structure that prevents separation between the metal part and dielectric member even when subjected to vibration or shock, and does not cause changes in the propagation mode.
The purpose is to provide a guide.

バ部を左右方向に延出させて断面Ｈ形に形成され、前記
ツバ部を含む誘電体部材の上下両端の外表面に金属膜が
密着形成されていることを特徴とする。In the NRD guide according to the present invention, the dielectric member has a vertical height perpendicular to the longitudinal direction of less than half a wavelength, and has collars extending in the left-right direction at both upper and lower ends to have an H-shaped cross section. A metal film is formed in close contact with the outer surface of both upper and lower ends of the dielectric member including the brim portion.

本発明にあっては、誘電体部材に、後述するようにスパ
ッタ、めっき及び印刷等を用いて金属を直接付着させて
形成すると、密着度を向上させ得るということを採用し
ている。このため、金属部形成用に誘電体部材自体を上
下両端にツバ部を有する断面Ｈ状としている。In the present invention, the degree of adhesion can be improved by directly attaching metal to a dielectric member using sputtering, plating, printing, etc. as described later. ing. For this reason, the dielectric member itself has an H-shaped cross section with flanges at both upper and lower ends for forming the metal portion.
而して、かかる断面形状の誘電体部材の上下両端部外側
に密着形成された金属部と誘電体部材との間では、剥離
しにくい状態となる。Therefore, it becomes difficult for the dielectric member to separate from the metal portion that is formed in close contact with the outside of both the upper and lower ends of the dielectric member having such a cross-sectional shape.

１は、一体成形や切削にて作成するのが好ましい。Back - Tadaichi Group FIG. 1 is a perspective view showing the NRD guide according to the present invention. In the figure, 1 is a long dielectric member made of Teflon resin, and the vertical height h perpendicular to the longitudinal direction is set to be less than half a wavelength, and the upper and lower ends have brim extending in the left-right direction. Portions 1a and Ib are formed. This dielectric member 1 is preferably made by integral molding or cutting.

。なお、金属膜２用の材料としては上記アルミニウムに
限らず、ＮＲＤガイドとして適当な特性を有する他の金
属を使用してもよい。Metal films 2, 2 made of aluminum or the like are formed on the outer surfaces of both upper and lower ends of the dielectric member 1, including the collar portions 1a, lb. To form the metal film 2, a film forming means that can be formed in close contact with Teflon resin, such as sputtering, plating, or printing, is used. Plating is used for metal film 2
This is because it can be formed in close contact with the dielectric member l. Note that the material for the metal film 2 is not limited to the above-mentioned aluminum, but other metals having suitable characteristics as an NRD guide may be used.
前記金属膜２，２は、機能的には第２図に示す従来の２
つの金属板１２．１２と同しである。このため、２つの
金属膜２．２の離隔間隔は、伝播モード、例えばＬ Ｓ
Ｍ ｏ ＋モードの半波長以下となるように設計しで
ある。The metal films 2, 2 are functionally similar to the conventional 2 shown in FIG.
It is the same as the two metal plates 12.12. For this reason, the separation between the two metal films 2.2 is determined by the propagation mode, for example L S
It is designed to be less than half the wavelength of the M o + mode.
一方、誘電体部材１はミリ波の伝送線路として主として
機能するが、ツバ部１ａ、ｌｂは、金属膜２，２を支持
する機能をもつだけで、伝送線路としての機能はない。On the other hand, the dielectric member 1 mainly functions as a millimeter wave transmission line, but the flange portions 1a and lb only have the function of supporting the metal films 2, 2 and do not function as a transmission line.
従って、ツバ部１ａ、ｌｂの厚みｔとしては、伝送線路
として機能する、つまりツバ部１ａ、ｌｂを除く誘電体
部材１部分の幅Ｗよりも十分に小さくなるように形成し
ておく。Therefore, the thickness t of the flange portions 1a and lb is set to be sufficiently smaller than the width W of the portion of the dielectric member 1 that functions as a transmission line, that is, excluding the flange portions 1a and lb.
こうすることによって、ツバ部により伝播モードが乱れ
るのを抑制できる。なお、図中の実線はＬＳＭｏ＋モー
ドのときの電気力線であり、破線はその磁力線である（
第２図の場合も同様である）。By doing so, it is possible to suppress disturbance of the propagation mode due to the flange portion. The solid lines in the figure are the electric lines of force in LSMo+ mode, and the broken lines are the magnetic lines of force (
The same applies to the case of Fig. 2).
また、ツバ部１ａ、ｌｂの左右方向の幅ｌについては、
テフロン樹脂の場合には伝送線路部分、つまりツバ部１
ａ、ｌｂを除く誘電体部材１部分の ４゜幅Ｗの３倍程
度あればよく、誘電率の高い樹脂やセラミックを用いる
場合には２倍程度としてもよい。Also, regarding the width l in the left and right direction of the brim portions 1a and lb,
In the case of Teflon resin, the transmission line part, that is, the collar part 1
It may be about three times the 4° width W of one portion of the dielectric member excluding a and lb, and may be about twice when a resin or ceramic with a high dielectric constant is used.
なお、上記実施例では金属膜が上下方向で対向するよう
にしているが、本発明は、金属膜を上下方向で対向させ
たものを横に倒して、金属膜が左右方向に位置するよう
になしたものも含むことは勿論である。In the above embodiment, the metal films are arranged to face each other in the vertical direction, but in the present invention, the metal films are arranged to face each other in the vertical direction and are laterally laid down, so that the metal films are positioned in the left-right direction. Of course, it also includes those who have done so.
また、上記実施例では誘電体部材がテフロン樹脂の場合
を例に挙げているが、本発明は接着を行い難い他の樹脂
やセラミック等からなるものにも同様に適用可能である
。Further, in the above embodiments, the dielectric member is made of Teflon resin, but the present invention is equally applicable to materials made of other resins, ceramics, etc. that are difficult to bond.
発旦生四果
以上詳述した如く本発明による場合には、誘電体部材の
ツバ部を含む上下両端の外面に金属膜が密着形成された
構成であるので、振動や衝撃を受けても金属部と誘電体

れるという優れた効果を奏する。As described in detail above, in the case of the present invention, the metal film is closely formed on the outer surface of both the upper and lower ends including the brim portion of the dielectric member, so that the metal film remains intact even when subjected to vibration or impact. This has an excellent effect of preventing separation between the part and the dielectric member and providing stable performance.
