【発明の属する技術分野】
本発明は、ラジオ及びテレビ放送等の受信に適する自動車用窓ガラスアンテナ装置に関する。
【０００２】
【従来の技術】
ラジオ及びテレビ放送等の受信用の自動車用窓ガラスアンテナ装置として、前置増幅器を用いていた装置では、車体にボルト等により取り付けたアンテナ周辺回路とアンテナ導体の給電点とをリード線によって接続していた。アンテナ周辺回路の出力端は受信機と接続されており、アンテナ周辺回路の出力信号は受信機に送られていた。
【０００３】
しかし、この従来例では、リード線もアンテナとして機能するために、リード線の長さ、リード線と車体との間隔等の要因によりアンテナ特性が不安定となる問題があった。
【０００４】
【発明が解決しようとする課題】
本発明は、従来技術の有する前述の欠点を解消する自動車用窓ガラスアンテナ装置の提供を目的とする。
【０００５】
【課題を解決するための手段】
本発明は、アンテナ導体及びアンテナ導体の給電点が自動車の窓ガラス板に設けられており、給電点の受信信号がアンテナ周辺回路を介して受信機に送られる自動車用窓ガラスアンテナ装置において、
アンテナ周辺回路とアンテナ周辺回路の入力端とが回路基板に設けられており、

【０００６】
また、アンテナ導体及びアンテナ導体の給電点が自動車の窓ガラス板に設けられており、給電点の受信信号がアンテナ周辺回路を介して受信機に送られる自動車用窓ガラスアンテナ装置において、
アンテナ周辺回路とアンテナ周辺回路の入力端とが回路基板に設けられており、
アンテナ周辺回路の入力端と給電点とが相対向するように回路基板が配されており、
アンテナ周辺回路の入力端と給電点との間に導電性接着剤又は半田が設けられており、
アンテナ周辺回路の入力端と給電点とが導電性接着剤又は半田により接続されていることを特徴とする自動車用窓ガラスアンテナ装置を提供する。
【０００７】
【発明の実施の形態】
以下、本発明を図面に従って詳細に説明する。図１は本発明の自動車用ガラスアンテナ装置の一実施例の構成及び製作する過程を示す模式図である。
【０００８】
図１において、１は自動車の窓ガラス板、３はアンテナ導体、３ａはアンテナ導体３の給電点、４は筐体、４ａは雌型コネクタ、４ｂは接着剤、４ｃは導電性弾性体、５は同軸ケーブル、５ａは雄型コネクタ、６はアースプレート、６ａはアースプレート６に設けられている孔、６ｂはアースプレート６に設けられている金属片、７は必要に応じて設けられるアンテナ周辺回路のアース用のリード線である。
【０００９】
図１に示す例では、アンテナ導体３及び給電点３ａが窓ガラス板１に設けられている。給電点３ａの受信信号が筐体４に収納されているアンテナ周辺回路（不図示）を介して受信機（不図示）に送られる。
【００１０】
図１に示す例では、アンテナ周辺回路とアンテナ周辺回路の入力端（不図示）とが回路基板に設けられており、回路基板は筐体４に収納されている。このように、この回路基板が筐体４に収納されていることが、アンテナ周辺回路を保護する上で好ましい。しかし、これに限定されず、この回路基板が筐体４に収納されていなくともよい。また、アンテナ周辺回路を保護するために、回路基板が収納されている筐体４に合成樹脂を充填し、筐体４に収納されている回路基板の周囲を合成樹脂で覆ってもよい。
【００１１】
また、回路基板を筐体４に収納しない場合であっても、アンテナ周辺回路を保護するために、回路基板の周囲を合成樹脂で覆い合成樹脂によりモールドすることが好ましい。なお、本発明において、回路基板の周囲を合成樹脂でモールドした場合には、筐体４をモールドした合成樹脂と言い換えられるものとする。
【００１２】
筐体４の材質については、ノイズ防止等の観点から鉄、アルミニウム等の金属が好ましいが、合成樹脂であっても使用できる。筐体４の寸法は、できるだけ小型化を図るため、長さが３０〜６０ｍｍ、幅が１０〜３０ｍｍ、高さが５〜２０ｍｍが好ましい。
【００１３】
図１に示す例では、未だ、筐体４を窓ガラス板１に設けていないときの状態を示している。筐体４を窓ガラス板１に設けるには、アンテナ周辺回路の入力端が給電点３ａと相対向するように、筐体４の位置及び筐体４の方向、言い換えれば、回路基板の位置及び回路基板の方向を定め、窓ガラス板１に垂直な方向であって窓ガラス板１の方向（図１の矢印の方向）に筐体４を移動して接着剤４ｂを窓ガラス板１に押圧するようにする。なお、接着剤４ｂはアンテナ周辺回路の入力端が設けられている領域以外の、回路基板の領域又は筐体４の領域と、給電点３ａ以外の領域の窓ガラス板の領域との間に介在するように設けられている。
【００１４】
図１に示す例では、接着剤４ｂにより筐体４を窓ガラス板１に装着すると、アンテナ周辺回路の入力端に接続されている導電性弾性体４ｃが給電点３ａに押し付けられ、アンテナ周辺回路の入力端と給電点３ａとが接続される。すなわち、アンテナ周辺回路の入力端が給電点とが相対向するように回路基板が配され、アンテナ周辺回路の入力端と給電点との間に導電性弾性体が設けられて、アンテナ周辺回路の入力端と給電点とが導電性弾性体を介して接続されている
なお、図１には示されていないが、導電性弾性体４ｃは回路基板に設けられているアンテナ周辺回路の入力端と給電点３ａとの間に挟まれることとなる。なお、アンテナ周辺回路の入力端と給電点３ａとの接続に導電性弾性体４ｃを用いることが生産性向上のために好ましい。しかし、これに限定されず、アンテナ周辺回路の入力端と給電点３ａとを導電性接着剤又は半田により接続してもよい。
【００１５】
アンテナ周辺回路の入力端と給電点３ａとの接続に導電性弾性体４ｃを用いる場合には、アンテナ周辺回路の入力端と給電点３ａとの間の抵抗値が、１．０Ω以下になるようにすることがアンテナ特性を向上させるため好ましく、この抵抗値が、１．０Ω以下になるように導電性弾性体４ｃの材質、形状及び寸法を特定することが好ましい。なお、導電性弾性体４ｃの厚さ（アンテナ周辺回路の入力端と給電点３ａとの間隔）は、３．０〜１０．０ｍｍが好ましい。
【００１６】
導電性弾性体４ｃが有する弾性物質の材質は、弾性に優れておりアンテナ周辺回路の入力端と給電点３ａとの接続を確実にさせるのでポリウレタンが好ましい。しかし、これに限定されず、ゴム、ポリエチレン及びシリコンゴム等も使用できる。導電性弾性体４ｃが有する弾性物質に含有させ、この弾性物質に導電性を持たせるための導電性物質の材質は、カーボン、銀、鉛及び錫等が挙げられる。これらの導電性物質は導電性に優れているために好ましい。
【００１７】
接着剤４ｂの材質は、接着剤４ｂの機能が、筐体４、回路基板又はモールドされた回路基板を窓ガラス板に接着することであるので、導電性を有さないのものでできるだけ絶縁性に優れたものを用いることが好ましい。接着剤４ｂの材質としては、接着力に優れている、シリコン含有の接着剤、ウレタン系の接着剤、エポキシ系の接着剤及び両面テープ等が挙げられる。
【００１８】
図１に示す例では、雌型コネクタ４ａが筐体４に設けられており、雌型コネクタ４ａはアンテナ周辺回路の出力端に接続されている。これに対して、雄型コネクタ５ａは同軸ケーブル５に接続されており、同軸ケーブル５の、雄型コネクタ５ａとは反対側の端部は受信機（不図示）に接続されている。雄型コネクタ５ａが雌型コネクタ４ａに勘合されることにより、雄型コネクタ５ａと雌型コネクタ４ａとが接続され、その結果、アンテナ周辺回路の出力端が受信機に接続される。
【００１９】
このように、図１に示す例では、アンテナ周辺回路の出力端と受信機とを、雄型コネクタ５ａと雌型コネクタ４ａとによって接続しているが、これに限定されず、アンテナ周辺回路の出力端と受信機との接続手段は限定されない。また、同軸ケーブル５の入力端をアンテナ周辺回路の出力端に半田付け等により接続することによりアンテナ周辺回路の出力端と受信機とを接続してもよい。
【００２０】
図１に示す例では、アンテナ周辺回路の接地をアースプレート６により行っている。アースプレート６は、アースプレート６に設けられている孔６ａにボルトを貫通させて車体に取り付けられ、アースプレート６と車体とは接続される。アンテナ周辺回路の接地に接続されているアース線７は必要に応じて設けられるものであり、アース線７は金属片６ｂを曲げて、アースプレート６と金属片６ｂとでアース線７を挟持するようにしてアース線７はアースプレート６に接続される。
【００２１】
本発明において、アンテナ周辺回路としては、インピーダンスマッチング回路、前置増幅回路、共振回路等が挙げられ、特に限定されない。本発明において、アンテナ導体３及び給電点３ａとは、通常、銀ペースト等の、導電性金属を含有するペーストを窓ガラス板１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、窓ガラス板１の車内側表面又は車外側表面に形成してもよく、窓ガラス板１自身の内部に設けてもよい。
【００２２】
【発明の効果】
本発明では、アンテナ周辺回路の入力端と給電点とが導電性弾性体を介して、又は、アンテナ周辺回路の入力端と給電点とが導電性接着剤又は半田により接続されているので、アンテナ周辺回路の入力端と給電点との間にリード線を接続する必要がないため、アンテナ特性が不安定となることが少ない。さらに、アンテナ周辺回路を窓ガラス板の上に設けるため、実装が容易で生産性も向上できる効果も認められる。
