In this connector, the holder part and the pickup part are detachably fitted, the holder part is soldered and connected to the glass antenna on the substrate, and the pickup part fitted into the holder part is Connected with coaxial cable. This connector will be briefly described with reference to FIGS. FIG. 8 is a six-side view of the holder portion of this connector.

このコネクタのホルダ部１５は、図８に示すように、直方体の２面が開口した形状の絶縁ケース１４の底部の両側に端子を配置されている。図８においては、底面図の右側が接地用端子１３、左側が給電用端子１２である。給電用端子１２は、絶縁ケース１４の内部に向かって立ち上がっている接続ピン１２ａを有し、この接続ピン１２ａは、図２Ａ，２Ｂに示すようなピックアップ部２１の嵌合端子２５を介して、同軸ケーブル２３の芯線２３ａと接続され、信号を同軸ケーブル２３側に伝送する（ピックアップ部２１の構造については、図２Ａ，２Ｂに示したものと同様である。）。接地用端子１３は、絶縁ケース１４の両側面内側に沿って立ち上がっている２つの接続部１３ａを有する。接続部１３ａは、ピックアップ部２１の接地用導体２４を介して同軸ケーブル２３の外周線２３ｃと連結する。絶縁ケース１４の長手方向両端部には、それぞれの端子の基板上のガラスアンテナとの接続部１２ｂ，１３ｂが突設されており、基板上のガラスアンテナとのハンダ付けが容易になっている。給電用端子１２及び接地用端子１３は、絶縁ケース１４の外側面を挟むようにして立ち上がっている２つずつの固定部１２ｃ，１３ｃによって、それぞれ絶縁ケース１４に固定されている。   As shown in FIG. 8, the connector holder portion 15 has terminals arranged on both sides of the bottom portion of the insulating case 14 having a shape in which two sides of a rectangular parallelepiped are opened. In FIG. 8, the right side of the bottom view is the grounding terminal 13, and the left side is the power feeding terminal 12. The power feeding terminal 12 has a connection pin 12a rising toward the inside of the insulating case 14, and this connection pin 12a is connected via a fitting terminal 25 of the pickup portion 21 as shown in FIGS. 2A and 2B. It is connected to the core wire 23a of the coaxial cable 23 and transmits a signal to the coaxial cable 23 side (the structure of the pickup unit 21 is the same as that shown in FIGS. 2A and 2B). The grounding terminal 13 has two connection portions 13 a rising along the inner sides of both sides of the insulating case 14. The connecting portion 13 a is connected to the outer peripheral line 23 c of the coaxial cable 23 via the grounding conductor 24 of the pickup portion 21. At both ends in the longitudinal direction of the insulating case 14, connecting portions 12b and 13b of the respective terminals to the glass antenna on the substrate are projected to facilitate soldering with the glass antenna on the substrate. The power supply terminal 12 and the grounding terminal 13 are fixed to the insulating case 14 by two fixing portions 12c and 13c that rise up with the outer surface of the insulating case 14 interposed therebetween.

図９は、このコネクタをガラス基板上のガラスアンテナに取り付けた状態の説明図である。ガラス基板５上のガラスアンテナの放射素子８の給電部と、コネクタ１１の給電用端子１２における装着部１２ｂとがハンダ付けされており、接地極６は接地用端子１３の装着部１３ｂとハンダ付けされている。なお、ガラスアンテナの形状、配置を表すＬＤ，ｐｄ，ｓ０，ｇ０などは、それぞれのガラスアンテナの受信特性によって決定される。図１０には、このコネクタを実際にガラス基板上のガラスアンテナに接続した状態の斜視図を示す。   FIG. 9 is an explanatory view showing a state in which this connector is attached to the glass antenna on the glass substrate.

Has been. Note that LD, pd, s0, g0 and the like representing the shape and arrangement of the glass antenna are determined by the reception characteristics of each glass antenna. FIG. 10 is a perspective view of the connector actually connected to the glass antenna on the glass substrate.

このようなコネクタは、例えば、非特許文献１に市販品として開示されている。また、特許文献１には、上述のようなガラスアンテナ用コネクタに、回路基板を内蔵させた回路基板内蔵コネクタが開示されている。特許文献２，３には、アンテナを設置した基板面に装着するホルダ部を、両面テープで貼着して固定し、このホルダ部に着脱自在で、給電端子の弾性力を利用してアンテナとの接続を可能にしたピックアップ部を備えた、簡単に固定及び着脱できるコネクタが開示されている。   Such a connector is disclosed as a commercial product in Non-Patent Document 1, for example. Patent Document 1 discloses a circuit board built-in connector in which a circuit board is built in the glass antenna connector as described above. In Patent Documents 2 and 3, a holder part to be attached to a substrate surface on which an antenna is installed is fixed by sticking with a double-sided tape, and the holder part is detachably attached to the antenna part using the elastic force of a power feeding terminal. There has been disclosed a connector that can be easily fixed and detached, including a pickup portion that enables the connection.

一方、特許文献４には、コネクタ部の信号伝送路における特性インピーダンスの急激な変化を抑制するため、同軸ケーブルの伝送路導体（芯線）と接続された中心導体を、アンテナを配置した基板面に対して傾斜して接続されるようにしたコネクタ装置が開示されている。

基板上に配置したガラスアンテナ（単にアンテナということがある。）と、同軸ケーブル等の伝送路とを接続する、非特許文献１、特許文献１〜３に開示されているようなコネクタは、高周波帯、特に極超短波帯（UHF帯）およびマイクロ波帯（SHF帯）などの周波数帯において、ガラス面に設置されたアンテナ（導体）とコネクタとの接合部で生じるインピーダンスの不整合による伝送ロスについては注意が払われていない。この為、アンテナから同軸ケーブルを通して受信機器まで伝送される信号の伝送ロスが大きく、受信機に正確な信号を伝送ができないことがある。特に、周波数がギガヘルツ領域の高周波帯に対応するアンテナの給電部では、使用される波長に対して基板面に設置したアンテナとコネクタとの接合部の形状が無視できない影響を及ぼし、アンテナの重要な構成要素である給電部の形状（寸法）が変形したと同様になり、信号の伝送特性に大きく影響を与えてしまうことがある。   A connector such as that disclosed in Non-Patent Document 1 and Patent Documents 1 to 3, which connects a glass antenna (sometimes simply referred to as an antenna) disposed on a substrate and a transmission line such as a coaxial cable, has a high frequency. Loss due to impedance mismatch at the joint between the antenna (conductor) installed on the glass surface and the connector in frequency bands such as the ultra-high frequency band (UHF band) and microwave band (SHF band) Is not paid attention. For this reason, the transmission loss of the signal transmitted from the antenna to the receiving device through the coaxial cable is large, and an accurate signal may not be transmitted to the receiver. In particular, in the antenna power supply section corresponding to the high frequency band in the gigahertz region, the shape of the joint between the antenna and the connector installed on the substrate surface has a non-negligible influence on the wavelength used, which is important for the antenna. This is the same as when the shape (dimension) of the power supply unit, which is a component, is changed, and may greatly affect the signal transmission characteristics.

地上波デジタルテレビ放送、欧州連合地域のデジタルテレビ放送、デジタルラジオ放送やＧＰＳなどに用いられる電波信号は、極超短波帯（UHF帯）の高周波数帯を利用している場合が多い。この為、このような高周波数帯の受信アンテナからの信号の伝送路においては、同軸ケーブルとコネクタのインピーダンスのマッチング、特に接続するアンテナやその基板の形状や性質を配慮したコネクタの設計が必要である。   Radio signals used for terrestrial digital television broadcasting, digital television broadcasting in the European Union, digital radio broadcasting, GPS, and the like often use the ultra-high frequency band (UHF band). For this reason, in the signal transmission path from such a high frequency band receiving antenna, it is necessary to match the impedance of the coaxial cable and the connector, and in particular, to design the connector in consideration of the shape and properties of the antenna to be connected and its board. is there.

特許文献４に開示されているコネクタ装置においては、伝送路におけるインピーダンスを考慮して、アンテナの給電部とコネクタの給電用端子の接続角度を規定しているが、コプレーナウェイブガイド線路が形成されているアンテナの給電部に、コネクタの給電端子を所定角度で接続する必要があり、接続の精度や信頼性、特にガラスアンテナに用いる場合には耐久性の確保が問題となる場合がある。   In the connector device disclosed in Patent Document 4, the connection angle between the antenna power supply unit and the connector power supply terminal is defined in consideration of the impedance in the transmission line, but a coplanar wave guide line is formed. It is necessary to connect the power supply terminal of the connector at a predetermined angle to the power supply part of the antenna, and ensuring the durability and accuracy of connection, particularly when used for a glass antenna, may be a problem.

一方、一般的なプリント基板などに実装される同軸ケーブル接続用のコネクタは、各種知られているが、これらは、車両用窓ガラスのように振動や外部応力のかかる可能性のある基板への実装を考慮しておらず、コネクタの嵌合性やその保持力、特に実装したコネクタ部分への外部応力に対して十分な耐性を有するとは言えない。   On the other hand, various types of connectors for connecting a coaxial cable mounted on a general printed circuit board are known, but these are used for a board that may be subjected to vibration or external stress, such as a vehicle window glass. Mounting is not taken into consideration, and it cannot be said that the connector has sufficient resistance against the fitting property and holding force thereof, in particular, external stress to the mounted connector portion.

本発明においては、上述の問題点をふまえ、高周波数帯の電気信号の伝送においても伝送路の伝送ロスを抑え、車両用窓ガラス等の基板への実装において信頼性、耐久性のあるコネクタの提供を目的としている。また、このコネクタを設置したアンテナ、及びこのアンテナを備えた車両用窓ガラスの提供を目的としている。   In the present invention, based on the above-mentioned problems, a transmission loss of a transmission path is suppressed even in the transmission of an electric signal in a high frequency band, and a reliable and durable connector is mounted on a substrate such as a vehicle window glass. The purpose is to provide. Moreover, it aims at provision of the antenna which installed this connector, and the window glass for vehicles provided with this antenna.

本発明のコネクタは、基板上のガラスアンテナに装着するホルダ部と、前記ホルダ部に着脱自在に嵌合し、同軸ケーブルに接続するピックアップ部とを備えるコネクタであって、前記ホルダ部は、一端が前記ガラスアンテナへの装着面に対し立ち上がって設置された、所定の幅を有する給電用端子と、前記給電用端子の他端の両側を所定の間隔をもって囲むように配置した接地用端子とを備え、前記ピックアップ部は、前記ホルダ部に装着された際に前記給電用端子の立ち上がっている端部と接続される嵌合端子と、前記嵌合端子と前記同軸ケーブルの芯線とを連結する芯線用導体と、前記同軸ケーブルの外周線と連結され、かつ前記ホルダ部に装着された際に前記接地用端子と接続される接地用導体とを備え、前記嵌合端子は、前記接地用導体に内包され、前記ホルダ部に前記ピックアップ部が装着された際の前記コネクタの特性インピーダンスは、前記同軸ケーブルと略等しい。 Connector of the present invention includes a holder portion for mounting the glass antenna on a substrate, fitted detachably in the holder part, a connector and a pickup portion for connecting to a coaxial cable, wherein the holder portion has one end And a power supply terminal having a predetermined width installed on the glass antenna mounting surface, and a ground terminal arranged so as to surround both sides of the other end of the power supply terminal with a predetermined interval. The pick-up unit is connected to a rising end of the power feeding terminal when the pickup unit is mounted on the holder unit, and a core wire for connecting the fitting terminal and the core wire of the coaxial cable And a grounding conductor connected to the grounding terminal when connected to the outer peripheral line of the coaxial cable and attached to the holder portion, and the fitting terminal is connected to the grounding terminal. Encapsulated in the body, the characteristic impedance of the connector when the pickup portion to the holder portion is mounted is substantially equal to said coaxial cable.

テレビ等に使用されている同軸ケーブルのインピーダンスは、５０〜７５Ω程度のものが多く、このコネクタは使用する同軸ケーブルを想定してそのインピーダンスを設計されている。また、具体的な本発明のコネクタの設計において、給電用端子の幅及びその両側を挟む接地用端子との間隔は、装着する基板やガラスアンテナの形状、性質等を考慮して設計されている。例えば、ガラスアンテナに形成されているコプレーナウェイブガイド線路の機能に影響を与えないように、給電用端子の幅及び給電用端子と接地用端子の間隔を設定する。   The impedance of a coaxial cable used in a television or the like is often about 50 to 75Ω, and this connector is designed assuming the coaxial cable to be used. Further, in the specific design of the connector of the present invention, the width of the power supply terminal and the distance from the ground terminal sandwiching both sides thereof are designed in consideration of the shape and properties of the substrate to be mounted and the glass antenna. . For example, the width of the power feeding terminal and the interval between the power feeding terminal and the ground terminal are set so as not to affect the function of the coplanar wave guide line formed in the glass antenna.

本発明のコネクタは、超短波帯（VHF帯）、極超短波帯（UHF帯）、マイクロ波帯（SHF帯）等の高周波用、特にギガヘルツ周波数帯の受信用ガラスアンテナからの信号伝送に適する面実装型のコネクタである。基板の表面に形成された伝送線路、例えばガラス板上に設けられたガラスアンテナの給電線路に接続が容易で、コネクタ及びこれに接続された同軸ケーブルを含む伝送路の信号伝送ロスが少ない面実装型のコネクタである。また、基板への装着が容易なように、ホルダ部とピックアップ部を着脱自在に嵌合できる構造にしている。   The connector of the present invention is a surface mount suitable for signal transmission from a receiving glass antenna for a high frequency such as a very high frequency band (VHF band), a very high frequency band (UHF band), a microwave band (SHF band), etc., particularly a gigahertz frequency band. Type connector. Surface mounting that is easy to connect to a transmission line formed on the surface of a substrate, for example, a glass antenna feeding line provided on a glass plate, and that has a small signal transmission loss in a transmission line including a connector and a coaxial cable connected thereto. Type connector. Further, the holder part and the pickup part can be detachably fitted so as to be easily mounted on the substrate.

そして、本発明のコネクタは、前記コネクタの前記給電用端子と前記接地用端子とが、コプレーナウェイブガイド線路を構成している。 In the connector of the present invention, the power feeding terminal and the grounding terminal of the connector constitute a coplanar wave guide line.

給電用端子とその両側に所定の間隔をもって配置した接地用端子が、ガラスアンテナと接続された際に、コプレーナウェイブガイド線路を構成しており、その特性インピーダンスが同軸ケーブルとほぼ等しければ、高周波の電波信号に対しても給電用端子がアンテナの作用を示すことが少なく、ほぼ伝送路としての機能のみを発揮するので、アンテナ側から受ける信号を同軸ケーブルとともに効率よく受信機器に伝送することができる。さらに、ガラスアンテナとの接続部において、アンテナのコプレーナウェイブガイド線路部分の役割を担うこともできる。   When the power feeding terminal and the grounding terminal arranged at a predetermined interval on both sides of the power feeding terminal are connected to the glass antenna, a coplanar wave guide line is formed. Even for radio signals, the power feeding terminal rarely shows the function of the antenna, and almost functions only as a transmission path, so that the signal received from the antenna side can be efficiently transmitted to the receiving device together with the coaxial cable. . Furthermore, in the connection part with a glass antenna, it can also play the role of the coplanar wave guide line part of an antenna.

そして、本発明のコネクタは、前記接地用端子が前記ホルダ部のガラスアンテナへの装着面の長手方向両端に突設された装着部を有し、前記給電用端子が前記ホルダ部のガラスアンテナへの装着面の短手方向に突設された装着部を有している。 In the connector of the present invention, the grounding terminal has mounting portions protruding at both ends in the longitudinal direction of the mounting surface of the holder portion to the glass antenna, and the power feeding terminal is connected to the glass antenna of the holder portion. And a mounting portion protruding in the short direction of the mounting surface.

コネクタを基板上のガラスアンテナに実装する際に、通常は、給電用端子と接地用端子のハンダ付けによっている。給電用端子及び接地用端子の一部が、コネクタの装着面から突設されていれば、ハンダ付けが容易であり、また確実なハンダ付けができる。さらに、コネクタの長手方向両端にハンダ付け部を有し、これと直交する短手方向に突設した端子のハンダ付け部も有することにより、このコネクタの基板面への固定は、強固で信頼性のあるものとなる。   When the connector is mounted on the glass antenna on the substrate, the feeding terminal and the grounding terminal are usually soldered. If a part of the power feeding terminal and the grounding terminal protrude from the connector mounting surface, soldering is easy and reliable soldering can be performed. Furthermore, by having soldered parts on both ends of the connector in the longitudinal direction and also having soldered parts for terminals protruding in the short direction perpendicular to the connector, this connector can be firmly fixed on the board surface. There will be something.

本発明のアンテナは、誘電体基板上に線条の放射素子とその給電部と接地極とを配置したアンテナ部を有し、上述の本発明のいずれかのコネクタを備え、このコネクタの給電用端子と前記放射素子が接続され、このコネクタの接地用端子と前記接地極が接続されている。   An antenna of the present invention has an antenna portion in which a linear radiating element, its feeding portion, and a grounding electrode are arranged on a dielectric substrate, and includes any of the above-described connectors of the present invention. A terminal and the radiating element are connected, and a ground terminal of the connector and the ground electrode are connected.

本発明のアンテナは、接地極と一つの放射素子とを有する所謂モノポールアンテナであり、このアンテナで高周波帯域の電波を受信する際に、コネクタ及び同軸ケーブルの伝送路において伝送ロスが起こりにくい設計が可能である。すなわち、本発明のアンテナは、アンテナ部での特性インピーダンスを所望の値に設計可能なアンテナであり、同軸ケーブル及びコネクタ部での特性インピーダンスを、アンテナ部の特性インピーダンスに容易に合わせることができる。   The antenna of the present invention is a so-called monopole antenna having a grounding electrode and one radiating element, and when receiving radio waves in a high frequency band with this antenna, a design in which transmission loss is unlikely to occur in the transmission path of the connector and the coaxial cable. Is possible. That is, the antenna of the present invention is an antenna that can be designed to have a desired characteristic impedance at the antenna section, and the characteristic impedance at the coaxial cable and the connector section can be easily matched to the characteristic impedance of the antenna section.

好ましい本発明のアンテナは、前記放射素子の一部と前記接地極とが、コプレーナウェイブガイド線路を形成している。コプレーナウェイブガイド線路は、アンテナの特性インピーダンスを所望の値とすることができるので、この部分にアンテナのコプレーナウェイブガイド線路を破壊しないようにコネクタを接続すれば、アンテナの受信部の長さや形状が変化せず、アンテナ部の特性インピーダンスも変化しないので、アンテナから所定の高周波電波を受信し、コネクタ及び同軸ケーブルの伝送路から、伝送ロスなく受信装置に信号を伝送することができる。   In a preferred antenna of the present invention, a part of the radiating element and the ground electrode form a coplanar wave guide line. Because the coplanar wave guide line can set the characteristic impedance of the antenna to a desired value, if the connector is connected to this part so as not to destroy the coplanar wave guide line of the antenna, the length and shape of the receiving part of the antenna can be reduced. Since it does not change and the characteristic impedance of the antenna portion does not change, a predetermined high frequency radio wave can be received from the antenna, and a signal can be transmitted from the transmission path of the connector and the coaxial cable to the receiving device without transmission loss.

本発明の車両用窓ガラスには、ガラス基板上に上記の本発明のアンテナが配置されている。車両に搭載されたテレビ等の受信機器や通信機器は、アンテナを必要とするものが多いが、最近は、窓ガラスに設置したアンテナが多い。このようなアンテナとして、上記の本発明のガラスアンテナは好適である。車両用のアンテナは、振動や物理的な応力に対する耐性が特に必要であり、又、比較的長期間の耐久性も要求される。本発明の車両用窓ガラスは、このような要求に好適に応えることができる。さらに、車両用の受信機器等は、受信電波の電波状態のよくない場所でも使用されるため、本発明の車両用窓ガラスは、アンテナ、コネクタ、同軸ケーブルを結合した伝送路において、優れた伝送性能を発揮できるので、良質な信号を受信機に伝送できる。   In the vehicle window glass of the present invention, the antenna of the present invention is disposed on a glass substrate. Many receiving devices such as televisions and communication devices mounted on vehicles require an antenna, but recently, there are many antennas installed on a window glass. As such an antenna, the glass antenna of the present invention is suitable. Vehicle antennas are particularly required to be resistant to vibration and physical stress, and are required to have a relatively long-term durability. The vehicle window glass of the present invention can suitably meet such a demand. Furthermore, since vehicle receiving devices and the like are also used in places where the radio wave condition of the received radio waves is not good, the vehicle window glass of the present invention has excellent transmission in a transmission path that combines an antenna, a connector, and a coaxial cable. Since the performance can be demonstrated, a high-quality signal can be transmitted to the receiver.

本発明によれば、高周波数帯の電気信号の伝送においても伝送路の伝送ロスを抑え、車両用窓ガラス等の基板への実装において信頼性、耐久性のあるコネクタを提供できる。また、このコネクタを備えたアンテナ、及びこのアンテナを設置した車両用窓ガラスを提供できる。   ADVANTAGE OF THE INVENTION According to this invention, the transmission loss of a transmission line can be suppressed also in the transmission of the electrical signal of a high frequency band, and a reliable and durable connector can be provided in mounting to board | substrates, such as a window glass for vehicles. Moreover, the antenna provided with this connector and the window glass for vehicles which installed this antenna can be provided.

The present invention is not limited to these embodiments and examples, and these embodiments and examples can be changed or modified without departing from the spirit and scope of the present invention.

（実施形態１）
本発明のコネクタは、ホルダ部とピックアップ部とが着脱自在に嵌合できるように構成されている。本発明の実施形態１のコネクタのホルダ部を図１の６面図（（ａ）正面図、（ｂ）右側面図、（ｃ）左側面図、（ｄ）平面図、（ｅ）底面図、（ｆ）背面図（裏面図））を示す。また、図２Ａには、本発明のコネクタのピックアップ部の６面図を、図２Ｂには、図２Ａの平面図（ｄ）の切断線Ａ−Ａ'における断面図を示す。図１〜２Ｂを参照にして、この実施形態のコネクタについて説明する。 (Embodiment 1)
The connector of this invention is comprised so that a holder part and a pick-up part can be detachably fitted. FIG. 6 is a six-side view ((a) front view, (b) right-side view, (c) left-side view, (d) plan view), and (e) bottom view of the holder portion of the connector according to Embodiment 1 of the present invention. (F) Rear view (back view)) is shown. 2A is a six-face view of the pickup portion of the connector of the present invention, and FIG. 2B is a cross-sectional view taken along the section line AA ′ of the plan view (d) of FIG. 2A. The connector of this embodiment will be described with reference to FIGS.

このコネクタのホルダ部１０は、図１に示すように、略中空直方体の２面が開口した形状の絶縁ケース４の底部に２つの端子を配置している。図８に示した従来のコネクタのホルダ部においては、底面の両端に接地用端子１３と給電用端子１２を備えていた。しかし、この実施形態のコネクタのホルダ部１０においては、底面の中央部付近に給電用端子２を備え、給電端子２の両側に給電用端子２から所定の間隔で隔離して配置した接地用端子３を備えている。   As shown in FIG. 1, the holder portion 10 of this connector has two terminals arranged at the bottom of an insulating case 4 having a shape in which two surfaces of a substantially hollow rectangular parallelepiped are opened. In the holder portion of the conventional connector shown in FIG. 8, the grounding terminal 13 and the power feeding terminal 12 are provided at both ends of the bottom surface. However, in the connector holder portion 10 of this embodiment, the power supply terminal 2 is provided near the center of the bottom surface, and the grounding terminal is arranged on both sides of the power supply terminal 2 and separated from the power supply terminal 2 at a predetermined interval. 3 is provided.

図１の底面図（ｅ）に示す給電用端子２の幅ａ、及び給電用端子２とその両側の接地用端子３との間隔ｂは、このコネクタにより接続されたアンテナから同軸ケーブルに電波信号を伝送したときに、信号の伝送ロスが少なくなるように設計されている。すなわち、同軸ケーブルと接続されたコネクタを所定のアンテナと接続したときに、アンテナとコネクタとの接続部となる給電用端子２及び接地用端子３は、受信しようとしている電波に対してコプレーナウェイブガイド線路構造を有している。このようにすることで、給電用端子２のコプレーナウェイブガイド線路構造部分が受信電波信号に対して、所定の特性インピーダンスを示し、同軸ケーブルにコネクタを接続した伝送路の特性インピーダンスを、アンテナの特性インピーダンスと同じとすることができる。なお、この給電用端子２の幅ａ、及び給電用端子２と接地用端子３との間隔ｂは、コネクタを接続しようとしているアンテナの形状や、基板の誘電率などにより設定される値であり、追って説明するが、接続するアンテナの条件を勘案して設計される。   The width a of the power feeding terminal 2 shown in the bottom view (e) of FIG. 1 and the distance b between the power feeding terminal 2 and the ground terminals 3 on both sides thereof are transmitted from the antenna connected by this connector to the coaxial cable. It is designed to reduce the signal transmission loss when transmitting the signal. That is, when the connector connected to the coaxial cable is connected to a predetermined antenna, the power feeding terminal 2 and the grounding terminal 3 that are the connection portion between the antenna and the connector are coplanar wave guides for radio waves to be received. It has a track structure. By doing so, the coplanar wave guide line structure portion of the power feeding terminal 2 exhibits a predetermined characteristic impedance with respect to the received radio wave signal, and the characteristic impedance of the transmission line in which the connector is connected to the coaxial cable is set to the antenna characteristic. It can be the same as the impedance. The width a of the power feeding terminal 2 and the distance b between the power feeding terminal 2 and the grounding terminal 3 are values set by the shape of the antenna to which the connector is to be connected, the dielectric constant of the substrate, and the like. As will be described later, it is designed in consideration of the conditions of the antenna to be connected.

給電用端子２は、絶縁ケース４の内部に向かって立ち上がっている接続ピン２ａを有し、この接続ピン２ａは、図２Ａに示したピックアップ部２１の嵌合端子２５を介して、同軸ケーブル２３の芯線２３ａと接続され、給電用端子２に入力された信号を同軸ケーブル２３側に伝送する。   The power feeding terminal 2 has a connection pin 2a rising toward the inside of the insulating case 4, and the connection pin 2a is connected to the coaxial cable 23 via the fitting terminal 25 of the pickup unit 21 shown in FIG. 2A. The signal input to the power feeding terminal 2 is transmitted to the coaxial cable 23 side.

接地用端子３は、絶縁ケース４の短手方向両側面の内側に沿って立ち上がっている２つの接続部３ａを有する。接続部３ａは、図２Ａに示すピックアップ部２１側の接地用導体２４の接続部２４ａ、固定部（かしめ部）２４ｂを介して、同軸ケーブル２３の外周線２３ｂと接続される。なお、ホルダ部１０側の接続部３ａは、図１（ｂ）に示すように絶縁ケース４の内側に膨らんでおり、その弾性力により、ピックアップ部２１側の接地用導体２４の側面の接続部２４ａを押圧しながら接続して、電気的導通の確実性を確保するとともに、ピックアップ部２１をホルダ部に嵌合した際の保持の機能も有している。   The grounding terminal 3 has two connection portions 3 a that rise along the inner sides of both sides in the short direction of the insulating case 4. The connecting portion 3a is connected to the outer peripheral line 23b of the coaxial cable 23 via the connecting portion 24a and the fixing portion (caulking portion) 24b of the grounding conductor 24 on the pickup portion 21 side shown in FIG. 2A. The connection portion 3a on the holder portion 10 side swells inside the insulating case 4 as shown in FIG. 1B, and due to its elastic force, the connection portion on the side surface of the grounding conductor 24 on the pickup portion 21 side. 24a is connected while pressing to ensure the reliability of electrical continuity, and also has a holding function when the pickup portion 21 is fitted to the holder portion.

The connection portion 3b, 3b between the grounding terminal 3 and the glass antenna on the substrate protrudes from the portion, and it becomes easy to solder the feeding portion of the radiation element of the glass antenna on the substrate and the ground electrode. ing. Further, by soldering both ends in the longitudinal direction of the bottom surface of the holder portion 10, the adhesive strength to the substrate and the durability are ensured.

図１に示すように、接地用端子３は、絶縁ケース４の正面及び裏面（短手方向）を挟むようにして立ち上がっている固定部３ｃ，３ｄによって、それぞれ絶縁ケース４に固定されている。なお、給電用端子２の両側の接地用端子３は、互いに導通されていることが好ましいが、離間していても、それぞれアンテナの接地極に接続された時点で導通されることになるため、問題ない。   As shown in FIG. 1, the grounding terminal 3 is fixed to the insulating case 4 by fixing portions 3 c and 3 d erected so as to sandwich the front surface and the back surface (short direction) of the insulating case 4. The grounding terminals 3 on both sides of the power feeding terminal 2 are preferably electrically connected to each other, but even if they are separated from each other, they are electrically connected when connected to the ground electrode of the antenna. no problem.

With reference to FIGS. 2A and 2B, the connector pickup portion 21 of this embodiment will be described. The pickup unit 21 is a hollow substantially rectangular parallelepiped insulation case 22, a connection portion 24 a that is connected to the connection portion 3 a of the holder portion 10, and a coaxial cable 23 that is introduced into the insulation case 22. The grounding conductor 24 having a fixing portion (caulking portion) 24b for caulking the outer peripheral wire 23b and the core wire 23a of the coaxial cable 23 and the connection pin 2a of the holder portion 10 are fitted to each other, and a signal from the connection pin 2a Is fitted to the core wire 23a.

嵌合端子２５は、嵌合端子固定絶縁ケース２６の内部に固定され、さらに嵌合端子固定絶縁ケース２６は接地用導体２４に内包されるように内部に固定されており、ホルダ部１０の接続部２ａと嵌合する嵌合部２５ａと芯線固定部（かしめ部）２５ｂを有している。芯線固定部（かしめ部）２５ｂと同軸ケーブルの芯線２３ａとはかしめて導通されている。そして、嵌合端子２５、嵌合端子固定絶縁ケース２６を含む接地用導体２４は絶縁ケース２２に内包されるように内部に固定される。   The fitting terminal 25 is fixed inside the fitting terminal fixing insulating case 26, and the fitting terminal fixing insulating case 26 is fixed inside so as to be included in the grounding conductor 24. It has the fitting part 25a fitted to the part 2a, and the core wire fixing | fixed part (caulking part) 25b. The core wire fixing portion (caulking portion) 25b and the core wire 23a of the coaxial cable are caulked and electrically connected. The grounding conductor 24 including the fitting terminal 25 and the fitting terminal fixing insulating case 26 is fixed inside so as to be enclosed in the insulating case 22.

図３には、本発明の実施形態２のコネクタのホルダ部１０'の６面図（（ａ）正面図、（ｂ）右側面図、（ｃ）左側面図、（ｄ）平面図、（ｅ）底面図、（ｆ）背面図）を示した。図３のコネクタと実施形態１のコネクタとの相違部分について説明する。このコネクタにおいては、ホルダ部１０'の接地端子３が一枚の金属板から形成されており、接地端子３の両端部３ｂ，３ｂが接続されている。そして、絶縁ケース４の底面が欠落しており、底面の代わりに底部固定バー４ａ，４ｂが配置されている。給電端子２は、底部固定バー４ｂにより絶縁ケース４に固定されており、絶縁ケース４の底部から裏面（短手）方向に付きだしてはいない。給電端子２が絶縁ケース４の底部から付きだしていないと、アンテナの放射素子とのハンダ付けが困難になるが、接地端子の両端の接着部３ｂ，３ｂをガラスアンテナにハンダ付けしておけば、金属製の給電端子２の弾性力を利用してアンテナの放射素子との導通は確保できる。このコネクタのその他の部分は、実施形態１のコネクタとほぼ同じであるので、その他の部分については、実施形態１のコネクタの説明を参照すればよい。 (Embodiment 2)
FIG. 3 includes six views ((a) front view, (b) right side view, (c) left side view, (d) plan view) of the holder portion 10 'of the connector according to Embodiment 2 of the present invention. e) bottom view, (f) rear view). Differences between the connector of FIG. 3 and the connector of Embodiment 1 will be described. In this connector, the ground terminal 3 of the holder portion 10 'is formed from a single metal plate, and both end portions 3b, 3b of the ground terminal 3 are connected. The bottom surface of the insulating case 4 is missing, and the bottom fixing bars 4a and 4b are arranged instead of the bottom surface. The power feeding terminal 2 is fixed to the insulating case 4 by the bottom fixing bar 4b, and does not stick out from the bottom of the insulating case 4 in the back surface (short side) direction. If the power supply terminal 2 is not attached from the bottom of the insulating case 4, it is difficult to solder the antenna to the radiating element. However, if the adhesive portions 3b and 3b at both ends of the ground terminal are soldered to the glass antenna. The continuity between the antenna and the radiating element can be ensured by utilizing the elastic force of the metal feeding terminal 2. Other parts of this connector are almost the same as those of the connector of the first embodiment, so the description of the connector of the first embodiment may be referred to for other parts.

実施形態３は、上述の実施形態１のコネクタを備えた本発明のガラスアンテナである。図４にこのアンテナの配置説明図を、図５にガラス基板５上に装着した実施形態３のアンテナの斜視図を示す。このアンテナは、図４に示すように、誘電体であるガラス基板５上に接地極６と線状の放射素子７とが配置され、放射素子７の一部は、接地極６とコプレーナウェイブガイド線路を構成している。コプレーナウェイブガイド線路（Ｃｏｐｌａｎａｒ Ｗａｖｅｇｕｉｄｅ線路：以下ＣＰＷ線路という。）とは、誘電体基板上に配置された一定幅の中央導体（この場合、放射素子７の長さＬｔの部分）が、外側導体（この場合、接地極６のうち中央導体を挟む部分）により所定の間隔で両側から挟まれた伝送線路であり、外側導体を接地導体としておけば、中央導体は特定の特性インピーダンスを有する伝送路とすることができる。なお、中央導体と外側導体の間隔Ｗは、誘電体基板の誘電率や厚さ、中央導体の幅ｓ、中央導体及び外側導体の導電率、などにより決定される。ＣＰＷ線路は、図４における放射素子７のＬｔで示される範囲に形成され、放射素子７の幅ｓ、両側の接地極６との間隔Ｗで構成される伝送線路である。そして、特性インピーダンスが所定の値、例えば５０Ωとなるように、中央導体の幅ｓと外側導体の距離ｗとの比が、ガラス基板５の厚さ及び比誘電率、中央導体や接地導体の導電率に基づいて設定される。このＣＰＷ線路の形成については、文献（例えば書名：ＭｉｃｒｏｓｔｒｉｐＬｉｎｅｓ ａｎｄ Ｓｌｏｔｌｉｎｅｓ 出版社：Ａｒｔｅｃｈ Ｈｏｕｓｅ著者：Ｋ．Ｃ．Ｇｕｐｔａ他）に詳述されているように周知事項である。 (Embodiment 3)
Embodiment 3 is a glass antenna of the present invention provided with the connector of Embodiment 1 described above. FIG. 4 is a diagram for explaining the arrangement of the antenna, and FIG. 5 is a perspective view of the antenna according to the third embodiment mounted on the glass substrate 5. In this antenna, as shown in FIG. 4, a grounding electrode 6 and a linear radiating element 7 are arranged on a glass substrate 5 that is a dielectric, and a part of the radiating element 7 includes a grounding electrode 6 and a coplanar wave guide. It constitutes a track. A coplanar wave guide line (Coplanar Waveguide line: hereinafter referred to as a CPW line) is a constant-width central conductor (in this case, a portion of the length Lt of the radiating element 7) disposed on a dielectric substrate. In this case, the transmission line is sandwiched from both sides by a predetermined interval by the portion of the ground electrode 6 sandwiching the center conductor), and if the outer conductor is a ground conductor, the center conductor is a transmission line having a specific characteristic impedance. can do. The interval W between the center conductor and the outer conductor is determined by the dielectric constant and thickness of the dielectric substrate, the width s of the center conductor, the conductivity of the center conductor and the outer conductor, and the like. The CPW line is a transmission line that is formed in a range indicated by Lt of the radiating element 7 in FIG. 4 and includes a width s of the radiating element 7 and a distance W between the grounding electrodes 6 on both sides. Then, the ratio of the width s of the central conductor to the distance w of the outer conductor is the thickness and relative dielectric constant of the glass substrate 5, the conductivity of the central conductor and the ground conductor so that the characteristic impedance becomes a predetermined value, for example, 50Ω. Set based on rate. The formation of this CPW line is a well-known matter as described in detail in the literature (for example, title: MicrostripLines and Slotlines Publisher: Arttech House Author: K. C. Gupta et al.).

コネクタ１は、給電用端子２の接地用端子３に挟まれた部分が放射素子７の中央導体部分と重なるようにガラス基板５上に配置される。このとき、給電用端子２の幅（図１におけるａ）は中央導体の幅ｓ以下である。また、給電用端子２を挟む接地用端子３の間の間隔（図１におけるａ＋２ｂ）は、中央導体を挟む外側導体間の間隔（ｓ＋２Ｗ）以上である。すなわち、コネクタ１の給電用端子２とこれを挟む接地用端子３との間隔（図１におけるｂ）は、中央導体とこれを挟む外側導体との間隔（Ｗ）と同じか、広くなっている。このようにして、中央導体と給電用端子２、及び外側導体と接地用端子３を接続したときに、この部分が幅ｓの中央導体と間隔Ｗをおいて配置された外側導体のＣＰＷ線路としての構造が保たれるようになっている。   The connector 1 is disposed on the glass substrate 5 so that the portion sandwiched between the grounding terminals 3 of the power feeding terminals 2 overlaps the central conductor portion of the radiating element 7. At this time, the width of the power feeding terminal 2 (a in FIG. 1) is equal to or smaller than the width s of the central conductor. Further, the distance between the ground terminals 3 sandwiching the power supply terminal 2 (a + 2b in FIG. 1) is equal to or greater than the distance between the outer conductors sandwiching the central conductor (s + 2W). That is, the distance (b in FIG. 1) between the power feeding terminal 2 of the connector 1 and the grounding terminal 3 sandwiching it is the same as or wider than the distance (W) between the central conductor and the outer conductor sandwiching it. . In this way, when the central conductor and the power feeding terminal 2 and the outer conductor and the grounding terminal 3 are connected, this portion serves as a CPW line of the outer conductor arranged at a distance W from the central conductor having the width s. The structure of is to be maintained.

なお、コネクタ１の給電用端子２とこれを挟む接地用端子３との間隔が、このアンテナに適したＣＰＷ線路を形成している場合（図１におけるａ＝ｓ，ｂ＝Ｗとなっている場合）、ガラス板５上の中央導体の幅及び中央導体と外側導体との間隔は、ＣＰＷ線路を構成していなくてもよい場合がある。すなわち、中央導体と給電用端子２、及び外側導体と接地用端子３を接続したときに、コネクタ１側の給電用端子２と接地用端子３が、ＣＰＷ線路としての中央導体の幅ｓとＣＰＷ線路としての外側導体の間隔Ｗを形成するので、ガラス基板５上の中央導体は幅ｓ以下でもよく、外側導体と給電用端子２との間隔がＷ以上であってもよい。これらの態様を纏めて言えば、中央導体と給電用端子２、及び外側導体と接地用端子３を接続したときに、中央導体と給電用端子２の接続部を一体の中央導体と見なし、外側導体と接地用端子３の接続部を一体の外側導体と見なすことができ、これらに対して中央導体の幅ｓ、中央導体と外側導体の間隔Ｗを、所望の特性インピーダンスを示す値とすればよい。   In addition, when the distance between the power feeding terminal 2 of the connector 1 and the grounding terminal 3 sandwiching the terminal forms a CPW line suitable for this antenna (a = s, b = W in FIG. 1). In some cases, the width of the central conductor on the glass plate 5 and the distance between the central conductor and the outer conductor may not constitute a CPW line. That is, when the central conductor and the power feeding terminal 2 and the outer conductor and the grounding terminal 3 are connected, the power feeding terminal 2 and the grounding terminal 3 on the connector 1 side have a width s and a CPW of the central conductor as a CPW line. Since the interval W between the outer conductors as a line is formed, the central conductor on the glass substrate 5 may have a width s or less, and the interval between the outer conductor and the power feeding terminal 2 may be W or more. In summary, when the central conductor and the power feeding terminal 2 and the outer conductor and the grounding terminal 3 are connected, the connecting portion of the central conductor and the power feeding terminal 2 is regarded as an integral central conductor, The connection portion between the conductor and the grounding terminal 3 can be regarded as an integral outer conductor, and the width s of the central conductor and the interval W between the central conductor and the outer conductor are values indicating the desired characteristic impedance. Good.

図４に示すアンテナの場合、放射素子７のＣＰＷ線路を形成していない部分、すなわち、長さＬｅの部分が電波信号の受信部に相当する。コネクタ１をガラス基板５上に配置するときは、コネクタ１の接地用端子３の両端部の装着部３ｂを接地極６にハンダ付けし、給電用端子２の装着部２ｂを放射素子７の受信部にハンダ付けする。これにより、コネクタ１のガラス基板５上への確実な固定と、放射素子７と給電用端子２及び接地極６と接地用端子３の確実な接続が実現できる。なお、コネクタ１をガラス基板５上に接続した後のアンテナは、放射素子７と給電用端子２及び接地極６と接地用端子３の一部が、一体となってＣＰＷ線路を形成しているので、コネクタ１のＣＰＷ線路形成部と、放射素子７と接地極６によるＣＰＷ線路形成部とを厳密に合わせて配置する必要はなく、放射素子７の長手方向にずれてコネクタ１を配置してもよい。これにより、放射素子７の信号受信部の長さＬｅを調整することができる場合がある。   In the case of the antenna shown in FIG. 4, a portion of the radiating element 7 where the CPW line is not formed, that is, a portion having a length Le corresponds to a radio wave signal receiving portion. When the connector 1 is disposed on the glass substrate 5, the mounting portions 3 b at both ends of the grounding terminal 3 of the connector 1 are soldered to the ground electrode 6, and the mounting portion 2 b of the power feeding terminal 2 is received by the radiating element 7. Solder to the part. Thereby, reliable fixation of the connector 1 on the glass substrate 5 and reliable connection of the radiating element 7, the power feeding terminal 2, the grounding electrode 6, and the grounding terminal 3 can be realized. In the antenna after the connector 1 is connected to the glass substrate 5, the radiation element 7, the power feeding terminal 2, the grounding electrode 6, and a part of the grounding terminal 3 integrally form a CPW line. Therefore, it is not necessary to arrange the CPW line forming part of the connector 1 and the CPW line forming part by the radiating element 7 and the grounding electrode 6 strictly, and the connector 1 is arranged by shifting in the longitudinal direction of the radiating element 7. Also good. Thereby, the length Le of the signal receiving part of the radiation element 7 may be able to be adjusted.

このように、ガラス基板５上の給電用端子２の接合部は、ＣＰＷ線路の形態を有しており、コネクタ１の接続ピン２ａ及び嵌合端子２５の距離は短いので、給電用端子２の接合部のＣＰＷ線路の特性インピーダンスと、同軸ケーブルの特性インピーダンス（通常高周波伝送路においては５０Ω程度）とを、ほぼ同じ値とすることで、アンテナから受信機までの伝送路の伝送損失を低減できる。   As described above, the joint portion of the power supply terminal 2 on the glass substrate 5 has a CPW line form, and the distance between the connection pin 2a of the connector 1 and the fitting terminal 25 is short. By making the characteristic impedance of the CPW line at the junction and the characteristic impedance of the coaxial cable (usually about 50Ω in a high-frequency transmission line) substantially the same value, the transmission loss of the transmission line from the antenna to the receiver can be reduced. .

なお、上述のガラス基板５は、接地極６の一部Ｌｔで示される範囲でＣＰＷ線路を構成し、ＣＰＷ線路の中央導体を延長してモノポールアンテナとしたものであるが、放射素子の形状はこれに限定されず、放射素子７の長さＬｅの部分の幅は、Ｌｔで示される範囲のＣＰＷ線路を構成する中央導体の幅ｓに比べて広くても良く、幅ｓから徐々に広くすることで、広帯域のアンテナとすることができる。さらには、扇状に広がっていても良く、複数本に分岐して、所望の周波数帯を受信できるアンテナパターン形成し、広帯域または多周波共用のアンテナとすることができる。そして、ＣＰＷ線路部分の長さＬｔも伝送損失を考慮の上適宜選択できる。   The glass substrate 5 described above constitutes a CPW line in a range indicated by a part Lt of the ground electrode 6 and extends a central conductor of the CPW line to form a monopole antenna. However, the width of the length Le portion of the radiating element 7 may be wider than the width s of the central conductor constituting the CPW line in the range indicated by Lt, and gradually increases from the width s. By doing so, it can be set as a broadband antenna. Furthermore, it may be spread in a fan shape, and an antenna pattern that can receive a desired frequency band can be formed by branching into a plurality of antennas, and a wideband or multi-frequency antenna can be obtained. The length Lt of the CPW line portion can be appropriately selected in consideration of transmission loss.

（実施形態４）
本発明に係るアンテナが実装されるガラス基板は、車両用のフロントガラス、ドアガラス、サイド窓ガラス及び後部窓ガラス等どのような車両用窓ガラスであってもよく、更には建築用の窓ガラスであってもよく、特に限定されない。図４のような構成とした場合、放射素子７と接地極６の少なくとも一部を隠蔽膜上に形成させることで、車外視において放射素子７の細い直線部分のみを見ることになり、デザイン上好ましい。 (Embodiment 4)
The glass substrate on which the antenna according to the present invention is mounted may be any vehicle window glass such as a vehicle windshield, door glass, side window glass, and rear window glass, and further, a window glass for architecture. There is no particular limitation. In the case of the configuration as shown in FIG. 4, by forming at least a part of the radiating element 7 and the ground electrode 6 on the concealing film, only the thin straight line portion of the radiating element 7 is seen in the vehicle external view. preferable.

一般に、車両用窓ガラス等に設置されたガラスアンテナにおいては、ガラス基板５上の導体（接地極６及び放射素子７）は、銀ペースト等の導電性金属を含有するペーストをガラス板の車内側表面にプリントし、焼付けて形成される。しかし、この形成方法に限定されず、銅等の導電性物質からなる、線状体又は箔状体を、ガラス基板上に形成してもよく、さらにはガラス基板上にこれらの導体を接着剤等により形成してもよい。   In general, in a glass antenna installed on a vehicle window glass or the like, a conductor (grounding electrode 6 and radiating element 7) on a glass substrate 5 is made of a paste containing a conductive metal such as a silver paste on the inside of the glass plate. It is formed by printing on the surface and baking. However, the present invention is not limited to this method, and a linear or foil-like body made of a conductive material such as copper may be formed on the glass substrate, and further, these conductors may be bonded onto the glass substrate. It may be formed by, for example.

ガラス基板５上の導体は銀導体によるものに係わらず、導体層を合成樹脂製フィルムの内部又はその表面に設け、導体層付き合成樹脂製フィルムをガラス板上に形成してもよい。さらに、導体が形成されたフレキシブル回路基板をガラス基板に形成してよい。   Regardless of whether the conductor on the glass substrate 5 is a silver conductor, a conductor layer may be provided inside or on the surface of the synthetic resin film, and the synthetic resin film with a conductor layer may be formed on the glass plate. Furthermore, you may form the flexible circuit board in which the conductor was formed in a glass substrate.

また、ガラス基板５の面上に隠蔽膜を形成し、この隠蔽膜の上に放射素子７と接地極６の一部分又は全体を設けてもよい。隠蔽膜は黒色セラミックス膜等のセラミックスが挙げられる。このガラス基板５を車両に適応し窓ガラスとした場合、窓ガラスの車外側から見ると、隠蔽膜により隠蔽膜上に設けられ導体の部分が車外から見えなくなり、デザインの優れた窓ガラスとなる。なお、ガラスアンテナは、必ずしもガラス基板上に設置されなくても、透明プラスチック基板のようにガラスに類似する基板上に設置される物でもよい。   Further, a concealing film may be formed on the surface of the glass substrate 5, and a part or the whole of the radiation element 7 and the ground electrode 6 may be provided on the concealing film. The concealing film may be a ceramic such as a black ceramic film. When this glass substrate 5 is adapted to a vehicle and used as a window glass, when viewed from the outside of the window glass, the window portion is provided on the shielding film by the shielding film so that the conductor portion is not visible from the outside of the vehicle, resulting in a window glass having an excellent design. . The glass antenna is not necessarily installed on the glass substrate, but may be an object installed on a substrate similar to glass, such as a transparent plastic substrate.

＜コネクタ１の製作＞
図１に示すホルダ部及び図２Ａ，２Ｂに示すピックアップ部からなるコネクタ１を作製した。但し、給電用端子２の接続ピン２ａは、円柱状ではなく、給電用端子２の接着部２ｂをそのまま９０度屈曲させて立ち上げた四角柱状のピンとした。 (Example)
<Production of connector 1>
A connector 1 including a holder portion shown in FIG. 1 and a pickup portion shown in FIGS. 2A and 2B was produced. However, the connection pin 2a of the power supply terminal 2 is not a columnar shape, but a square columnar pin that is raised by bending the adhesive portion 2b of the power supply terminal 2 as it is by 90 degrees.

このコネクタ１の図１における給電用端子２の幅ａは、２ｍｍ、給電用端子２と接地用端子３の間隔ｂは２ｍｍとした。ピックアップ部２１は、図２Ａ，２Ｂに示すピックアップ部とほぼ同じ市販のコネクタのピックアップ部を利用した。   The width a of the power supply terminal 2 in FIG. 1 of the connector 1 is 2 mm, and the distance b between the power supply terminal 2 and the ground terminal 3 is 2 mm. As the pickup unit 21, a commercially available connector pickup unit similar to the pickup unit shown in FIGS. 2A and 2B was used.

＜アンテナの製作＞
作製したコネクタ１のピックアップ部２１に、図２Ａ，２Ｂに示すように、特性インピーダンス５０Ωの同軸ケーブルを接続し、図４に示すように、ガラス基板上に設置したガラスアンテナの放射素子７の給電部及び接地極６に、このコネクタ１の給電用端子２と接地端子３をハンダ付けで固定した。ガラス基板上に設置したこのコネクタ１を備えたアンテナの斜視図を、図５に示した。 <Production of antenna>
As shown in FIGS. 2A and 2B, a coaxial cable having a characteristic impedance of 50Ω is connected to the pickup portion 21 of the manufactured connector 1, and as shown in FIG. 4, feeding of the radiation element 7 of the glass antenna placed on the glass substrate is performed. The power supply terminal 2 and the ground terminal 3 of the connector 1 were fixed to the part and the ground electrode 6 by soldering. A perspective view of an antenna provided with this connector 1 placed on a glass substrate is shown in FIG.

ガラス基板５は、厚さ３．５ｍｍであり、横３００ｍｍ×縦１５０ｍｍの銅箔により接地極６を形成し、図４に示すように、接地極６の一辺の中央部にＣＰＷ線路構造と約１．５ＧＨｚで共振する１／４波長モノポールのアンテナエレメントを形成した。図４に示す各部の寸法は、

図４において、破線で示す位置に作製したコネクタ１をガラス基板５に設置し、ハンダ付けにより実装した。実装後の図５の状態で、アンテナ性能指標の一つであるリターンロスの測定を行った。図６に示すリターンロスの測定結果から、１．５５ＧＨｚにおいてリターンロスは−１６ｄＢ（電圧定在波比１．３８）となり、モノポールアンテナによる十分な共振が観察され、コネクタ部分における伝送損失が生じていないことが判る。   In FIG. 4, the connector 1 produced in the position shown with a broken line was installed in the glass substrate 5, and it mounted by soldering. In the state of FIG. 5 after mounting, return loss, which is one of the antenna performance indexes, was measured. From the measurement result of the return loss shown in FIG. 6, the return loss is -16 dB (voltage standing wave ratio 1.38) at 1.55 GHz, and sufficient resonance by the monopole antenna is observed, resulting in transmission loss in the connector portion. You can see that it is not.

なお、厚さ３．５ｍｍのガラス板、ガラスの比誘電率は７、放射素子７及び接地極６の導体厚１０μｍにおいて放射素子７の中心導体の幅ｓを３ｍｍ、中心導体と接地極６との間隙ｗが１ｍｍのとき、ＣＰＷ線路の特性インピーダンスは５５Ωであった。この場合、特性インピーダンスが５０Ωとなるように、ガラス厚さ、導体厚を考慮して、導体幅ｓ、接地極６との距離ｗが決定されることが好ましいが、本実施例では実装性、ハンダ付け作業性を考慮して、ほぼ５０Ωに近い５５Ωとした。   A glass plate having a thickness of 3.5 mm, a glass having a relative dielectric constant of 7, a conductor thickness of 10 μm of the radiating element 7 and the ground electrode 6, the width s of the central conductor of the radiating element 7 is 3 mm, and the central conductor and the ground electrode 6 When the gap w was 1 mm, the characteristic impedance of the CPW line was 55Ω. In this case, it is preferable that the conductor width s and the distance w from the ground electrode 6 are determined in consideration of the glass thickness and the conductor thickness so that the characteristic impedance is 50Ω. Considering the soldering workability, it is set to 55Ω, which is almost 50Ω.

使用される同軸ケーブルおよびコネクタの特性インピーダンスが７５Ωである場合に、同様に特性インピーダンスが７５Ωとなるように、ガラス厚さ、放射素子７の幅と、実装性、ハンダ付け作業性を考慮して、放射素子７の幅ｓ、接地極６との距離ｗを決定し、上述の値から変更することも可能である。   When the characteristic impedance of the coaxial cable and connector used is 75Ω, the glass thickness, the width of the radiating element 7, the mountability, and the soldering workability are taken into consideration so that the characteristic impedance is similarly 75Ω. It is also possible to determine the width s of the radiating element 7 and the distance w from the ground electrode 6 and change the values from the above values.

なお、接地極６の形状はコネクタの電気特性評価において本実施例のとおりとしたが、車両用窓ガラス板において使用される場合には、その形状や使用される周波数により、特性を考慮しながら適宜変更が可能であり、メッシュ状に変更することも可能である。また、本実施例による接地用端子３の装着部３ｂは、従来例と同様なハンダ付け面積を有するので外部力に対しての耐力もあり、また同軸ケーブル２３の配線方向も従来と同じであるので、特に車両用窓ガラス板におけるガラスアンテナに対するコネクタとして好適に利用できる。   In addition, although the shape of the grounding electrode 6 was set as in the present embodiment in the electrical characteristic evaluation of the connector, when used in a vehicle window glass plate, the characteristics are taken into consideration depending on the shape and the frequency used. It can be changed as appropriate, and can be changed to a mesh shape. Further, the mounting portion 3b of the grounding terminal 3 according to the present embodiment has a soldering area similar to that of the conventional example, so that it has resistance against external force, and the wiring direction of the coaxial cable 23 is the same as that of the conventional example. Therefore, it can utilize suitably as a connector with respect to the glass antenna especially in the window glass board for vehicles.

The mounting portion 12 b of the power feeding terminal 12 of the holder portion is connected to the power feeding portion of the radiating element 8, and the mounting portion 13 b of the grounding terminal 13 is connected to the ground electrode 6. The holder unit 15 is connected to a pickup unit 21 connected with a coaxial cable 23, and a high frequency signal received by the glass antenna is transmitted to the coaxial cable 23. The return loss was measured for this transmission line in the same manner as in the example. As can be seen from the measurement results shown in FIG. 7, in the gigahertz frequency band region, the return loss is generally flat, and a sufficient resonance frequency region is not observed, and it is evaluated that the performance as an antenna cannot be exhibited.
