【考案の詳細な説明】
本考案は簡易な構成でより良好な特性を得る垂直変換回
路に関する。[Detailed Description of the Invention] The present invention relates to a vertical conversion circuit that obtains better characteristics with a simple configuration.
従来のこの種垂直変換回路の例を第１図に示す。An example of a conventional vertical conversion circuit of this type is shown in FIG.
金属ブ冶ツクＭＢの表面にストリップライン１０を、ま
たブ陥ツクＭＢに内蔵して同軸線路１を設け、同軸線路
１の中心導体２は金属ブ遁ツク表面より突出させ、スト
リップラインの導体１１とを導体３によって接続してい
る。A strip line 10 is provided on the surface of the metal block MB, and a coaxial line 1 is provided built into the block MB, with the center conductor 2 of the coaxial line 1 protruding from the surface of the metal block MB, are connected by a conductor 3.
したがって同軸線路の中心導体２とストリップラインの
導体１１とは直交配置されている。Therefore, the center conductor 2 of the coaxial line and the conductor 11 of the strip line are arranged orthogonally.
４は誘電体材料を詰めるか中空のままとし、１２は誘電
体基板とする。4 is filled with dielectric material or left hollow, and 12 is a dielectric substrate.
ストリップライン１０の一端から同軸線路１の方に信号
を伝送するとき、或いはその逆に伝送するとき、図示す
る垂直変換部が存在するため発生［−た電磁界の向きが
滑らかに変換されず、そのため第２図の破線Ａに示すよ
うな伝送特性が得られるに過ぎなかった。When transmitting a signal from one end of the strip line 10 to the coaxial line 1 or vice versa, the direction of the electromagnetic field generated is not smoothly converted due to the existence of the vertical conversion section shown in the figure. Therefore, only the transmission characteristics shown by the broken line A in FIG. 2 were obtained.
第２図の縦線は反射損失（（ｉｂ）、横軸は周波数（Ｇ
Ｈｚ）を示し、周波数７乃至１０ＧＨｚでは送出量と反
射量との差が１５ｄｂ以下となる程であった。The vertical line in Figure 2 is the return loss (ib), and the horizontal axis is the frequency (G
Hz), and at frequencies from 7 to 10 GHz, the difference between the amount of transmission and the amount of reflection was 15 db or less.
本考案の目的は前述の欠点を改善するため同軸線路側に
簡易な構造変更を与えることによ−って良好な特性の得
られる垂直変換回路を提供することにある。An object of the present invention is to provide a vertical conversion circuit which can obtain good characteristics by making simple structural changes to the coaxial line side in order to improve the above-mentioned drawbacks.
以下図面に示す本考案実施例について説明する。Embodiments of the present invention shown in the drawings will be described below.
第３図は本考案の第１実施例を示す側断面図で、同軸線
路１の中空のままとしていた部分４であってストリップ
ラインに近接した所に商品名テフロンのような合成樹脂
５を封入することにより、ストリップライン側から見た
同軸線路のインピーダンスを若干低下させる。FIG. 3 is a side sectional view showing the first embodiment of the present invention, in which a synthetic resin 5 such as Teflon (trade name) is sealed in a hollow portion 4 of the coaxial line 1 close to the strip line. By doing so, the impedance of the coaxial line as seen from the stripline side is slightly lowered.
この場合の特然は第２図に実線Ｂで示すように反射損失
が改善されている。What is special about this case is that the reflection loss is improved as shown by the solid line B in FIG.
この場合テフロンは同軸線路中心導体２を保持するガイ
ドとしての役目を果たす。In this case, Teflon serves as a guide for holding the coaxial line center conductor 2.
なお、本考案の第２実施例として同図中の４に予め誘導
体が充填されているときには、合成樹脂５は、当然イン
ピーダンスを下げるような材料を用いる必要がある。Incidentally, in the second embodiment of the present invention, when 4 in the figure is filled with a dielectric in advance, it is necessary to use a material that lowers the impedance as the synthetic resin 5.
このようにして本考案によると、同軸線路の内、外導体
について直径を変更するなど加工を行うことなく、単に
誘電体材料について封入など簡易な構造変更のみで伝送
特性の良好な垂直変換回路を得ているから実用上有効で
ある。In this way, according to the present invention, a vertical conversion circuit with good transmission characteristics can be created by simply changing the structure of the dielectric material, such as encapsulating it, without changing the diameter of the inner and outer conductors of the coaxial line. It is practically effective because it has been obtained.
また同軸線路とストリップラインの接続近傍に誘電体が
常に存在することにより同軸線路内導体の支持材と兼用
できる。Furthermore, since the dielectric is always present near the connection between the coaxial line and the strip line, it can also be used as a supporting material for the conductor in the coaxial line.
