本考案は、高周波用基板材料の特性を測定する装置に関する。 The present invention relates to a device for measuring the characteristics of a high frequency substrate material.
【０００２】 従来からある高周波材料の線路定数測定方法として、比誘電率εrを測定する ためのリング共振器法や、誘電正接tanδを測定するための円筒空洞共振器法等 がある。 また、IEEE TRANS-ACTIONS ON INSTRUMENTATION AND MEASUREMENT,VOL.38,NO. 2,APRIL 1989に掲載の”Precise Measurementsof Dissipation Factor in Micr- owave Prited Circuit Boards"(HIROYUKI TANAKA,FUMIAKI OKADA著）には、トリ プレート構造の直線線路共振器を用いて、上記２つの定数を測定する方法が開示 されている。As a conventional method of measuring a line constant of a high frequency material, there are a ring resonator method for measuring a relative permittivity ε r , a cylindrical cavity resonator method for measuring a dielectric loss tangent tan δ, and the like. In addition, the "Precise Measurements of Dissipation Factor in Micr-owave Prited Circuit Boards" (written by HIROYUKI TANAKA, FUMIAKI OKADA) published in IEEE TRANS-ACTIONS ON INSTRUMENTATION AND MEASUREMENT, VOL.38, NO. A method of measuring the above two constants using a linear line resonator having a structure is disclosed.

円筒空洞共振器法では、測定周波数毎に円筒空洞共振器そのものを製作せねば ならず、製作コストも測定の手間も大変であり、かつ誘電正接 tanδしか測定で きない。リング共振器法では、基本共振周波数とその整数倍の周波数で測定が可 能であり、測定試料及び測定治具の製作は比較的容易であるが、比誘電率εrの 測定しかできず、誘電正接tanδの測定方法が別途必要となる。 これに対し、上記「田中と岡田」の報告している方法は簡便な測定試料でｔａ
ｎ δと等価導電率σｅｆｆの両方を測定することができる方法であるが、測定試料
は トリプレート線路上にギャップを設ける必要があり、１つの測定試料について、 基本共振周波数を変化させながら測定することができない。またトリプレート線 路は外部との接続が難しく、不要伝搬モードが発生する恐れがある。また、高周 波用のフィルム基板等では、フィルムがカールしてしまいトリプレート線路をう まく形成できない恐れがある。In the cylindrical cavity method, the cylindrical cavity itself must be manufactured for each measurement frequency, the manufacturing cost and the labor of measurement are great, and only the dielectric loss tangent tanδ can be measured. With the ring resonator method, it is possible to measure at the fundamental resonance frequency and a frequency that is an integral multiple of it, and it is relatively easy to fabricate the measurement sample and measurement jig, but only the relative permittivity ε r can be measured. A separate method for measuring the dielectric loss tangent tan δ is required. On the other hand, the method reported by "Tanaka and Okada" above is a simple measurement sample.
This is a method that can measure both n δ and the equivalent conductivity σ eff, but the measurement sample needs to have a gap on the triplate line, and one measurement sample is measured while changing the fundamental resonance frequency. I can't. In addition, the triplate line is difficult to connect to the outside, and there is a risk that unwanted propagation modes will occur. Also, with a high frequency film substrate or the like, the film may be curled and the triplate line may not be formed well.

図１に示すように、本考案による測定治具は、ベクトルネットワークアナライ ザ等の測定機との接続点となるコネクタ１a，１bと、コネクタを固定するための 台となるコネクタベース金具２a，２bと、コネクタベース金具２a，２bと結合し 、測定対象であるトリプレート線路共振器を形成する回路基板５をコネクタ１a ，１bと結合させるために固定するための回路基板結合金具３a，３bとからなる 測定治具において、コネクタ１a，１bと測定対象であるトリプレート線路共振器 を形成する回路基板５フィルム基板等を使用した際にも線路の下に空間を設ける 。 本考案による測定治具の動作について、次に説明する。コネクタ１a，１bは 、それぞれコネクタを固定するための台となるコネクタベース金具２a，２bに固 定される。ベクトルネットワークアナライザ等の測定機はコネクタ１a，１bに接 続される。第２図にこの部分の拡大図を示す。コネクタ１a，１bの芯線は回路基 板５のトリプレート線路とは直接接続されず、ある一定の距離を持った空間を介 して容量性結合される。また、回路基板結合金具３a，３bはそれぞれ回路基板５ の端部を上下より加圧し密着させ、かつコネクタベース金具２a，２bと密着する ことにより、回路基板５のコネクタベース金具２a，２bに固定されたコネクタ１ a，１bの芯線部との結合距離を性格に保持し、かつ回路基板上の線路の上下には 十分な空間を設ける。 以上述べてきた方法により、本考案による測定治具は、コネクタ１a，１bは回 路基板５のトリプレート線路共振器とは直接接続されずある一定の距離を持った 空間を介して容量性結合されるので、この空間をギャップとして用いることによ り、トリプレート線路上にギャップを設ける必要がなくなり、任意の線路長のト リプレート線路共振器を測定する際にも、回路基板結合金具３a，３bの長さと同 じものであれば良い。 また、トリプレート線路共振器を製作する際もギャップを線路上につくる必要 がないので簡単に製作でき、例えば１個の測定試料を長めに製作しておいて、そ れをいろいろな長さの３a，３bに合わせて切断しながら（基本共振周波数を変化 させながら）測定すれば、試料製作の手間が簡略化できる。また、線路の下には 接地導体となる回路基板結合金具３a，３bとの間に十分な空間を設けることがで き、この間に任意の誘電率の誘電体を挟み込んだり、あるいは回路基板のすぐ下 に接地導体となる金属箔を挟み込んだりすることができ、種々の条件での測定が 可能となる。またフィルム基板のような薄い回路基板でも、基板端部で十分に張 力をかけた状態で上下から回路基板結合金具で固定すればトリプレート構造が保 持でき、正確な測定ができる。 As shown in FIG. 1, the measuring jig according to the present invention comprises connectors 1a and 1b which are connection points with a measuring machine such as a vector network analyzer, and a connector base metal fitting 2a which is a base for fixing the connector. 2b and circuit board coupling metal fittings 3a and 3b for fixing the circuit board 5 which is coupled with the connector base metal fittings 2a and 2b and forms the triplate line resonator to be measured to the connector 1a and 1b. In the measuring jig consisting of, the space is provided under the line even when the connector 1a, 1b and the circuit substrate 5 film substrate forming the triplate line resonator to be measured are used. The operation of the measuring jig according to the present invention will be described below. The connectors 1a and 1b are fixed to connector base metal fittings 2a and 2b, respectively, which serve as a base for fixing the connectors. Measuring instruments such as vector network analyzers are connected to connectors 1a and 1b. FIG. 2 shows an enlarged view of this portion. The core wires of the connectors 1a and 1b are not directly connected to the triplate line of the circuit board 5, but are capacitively coupled through a space having a certain distance. Further, the circuit board coupling fittings 3a and 3b are fixed to the connector base fittings 2a and 2b of the circuit board 5 by pressing the end portions of the circuit board 5 from above and below to make them adhere to each other and to make close contact with the connector base fittings 2a and 2b. The connection distance between the cores of the connectors 1a and 1b thus prepared is maintained, and a sufficient space is provided above and below the line on the circuit board. According to the method described above, the measuring jig according to the present invention is such that the connectors 1a and 1b are not directly connected to the triplate line resonator of the circuit board 5 but are capacitively coupled through a space having a certain distance. Therefore, by using this space as a gap, it is not necessary to provide a gap on the triplate line, and the circuit board coupling fitting 3a can be used even when measuring a triplate line resonator with an arbitrary line length. , 3b as long as the length. In addition, since it is not necessary to make a gap on the line when manufacturing a triplate line resonator, it can be easily made. For example, one measurement sample can be made long and then various lengths can be prepared. If the measurement is performed while cutting according to 3a and 3b (while changing the fundamental resonance frequency), the time and effort for sample preparation can be simplified. In addition, a sufficient space can be provided under the line between the circuit board coupling fittings 3a and 3b, which are ground conductors, and a dielectric material having an arbitrary permittivity can be sandwiched between them, or the space between the circuit board and It is possible to insert a metal foil that serves as a grounding conductor underneath, and it is possible to measure under various conditions. Even for thin circuit boards such as film boards, a triplate structure can be maintained and accurate measurements can be made by fixing the circuit board coupling fittings from above and below while applying sufficient tension at the board edges.
