【発明の属する技術分野】
本発明は、日本のラジオＦＭ放送帯（７６〜９０ＭＨｚ）、米国のラジオＦＭ放送帯（８８〜１０８ＭＨｚ）及びＡＭ放送帯（５３０〜１６０５ｋＨｚ）の受信に適する自動車用サイド窓ガラスアンテナに関する。
【０００２】
【従来の技術】
ＡＭ放送帯及びＦＭ放送帯受信用のサイド窓ガラスアンテナとして、従来、図２に示すような、自動車の略四角形の後部サイド窓ガラス板８に給電点７とアンテナ導体２３とが設けられているものを使用していた。
【０００３】
しかし、この従来例では、水平方向等間隔に１２本のエレメントを設けているため、視野が充分に確保できない。この欠点を解消するため、後部サイド窓ガラス板８の中央部のエレメントのいくつかを設けないようにすると、ＡＭ放送の感度の低下、ＦＭ放送の感度の低下及び指向性の劣化の問題が生じる。
【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し、視野が充分に確保しやすく、ＡＭ放送の感度の向上及びＦＭ放送の感度の向上が達成できる新規な自動車用サイド窓ガラスアンテナ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、前述の課題を解決すべくなされたものであり、自動車のサイド窓ガラス板（８）の車体開口縁（９）近傍に給電点（７）が設けられており、
給電点（７）又は給電点（７）から伸長される接続線条（６）にそれぞれの一端を接続している第１のアンテナ線条（１）、第２のアンテナ線条（２）及び第３のアンテナ線条（３）が、車体開口縁（９）に沿って時計回り方向に伸長され、サイド窓ガラス板（８）の周囲から中心に向かって、第１のアンテナ線条（１）、第２のアンテナ線条（２）、第３のアンテナ線条（３）の順に、かつ、それぞれが略平行になるようにサイド窓ガラス板（８）に設けられる一方、
給電点（７）又は給電点（７）から伸長される接続線条（６）に一端を接続している第４のアンテナ線条（４）が車体開口縁（９）に沿って反時計回り方向に伸長されて、サイド窓ガラス板（８）に設けられており、
ＦＭ放送帯の中心周波数の波長をλ M 、ガラス短縮率Ｋを０．６４とするとき、
第１のアンテナ線条（１）の長さ、及び、第２のアンテナ線条（２）の長さは、それぞれ０．３λ M ×Ｋ〜０．９λ M ×Ｋであり、
第３のアンテナ線条（３）の長さ、及び、第４のアンテナ線条（４）の長さは、それぞれ０．１５λ M ×Ｋ〜０．４λ M ×Ｋであり、
第１のアンテナ線条（１）と第４のアンテナ線条（４）とが略平行に近づいている部分があり、この略平行に近づいている部分の少なくとも１００ｍｍの長さについて、第１のアンテナ線条（１）と第４のアンテナ線条（４）との間の間隔が２６ｍｍ以上であり、
第２のアンテナ線条（２）と第４のアンテナ線条（４）とが略平行に近づいている部分があり、この略平行に近づいている部分の少なくとも１００ｍｍの長さについて、第２のアンテナ線条（２）と第４のアンテナ線条（４）との間の間隔が２６ｍｍ以上であることを特徴とする自動車用サイド窓ガラスアンテナを提供する。
【０００６】
【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サイド窓ガラスアンテナの一実施例の構成図であり、ＦＭ放送帯及びＡＭ放送帯を受信することを想定している。
【０００７】
図１に示す自動車用サイド窓ガラスアンテナでは、略四角形状の後部サイド窓ガラス板８の車体開口縁９近傍に給電点７が設けられている。ここで、車体開口縁９とは後部サイド窓ガラス板８がはめ込まれる車体の開口部の周縁であって車体アースとなるべきものをいい、例えば、金属等の導電性材料で構成されている。
【０００８】
給電点７から伸長される接続線条６にそれぞれの一端を接続している第１のアンテナ線条１、第２のアンテナ線条２及び第３のアンテナ線条３が、車体開口縁９に沿って時計回り方向に伸長されている。
【０００９】
このように給電点７から伸長される接続線条６に、第１のアンテナ線条１、第２のアンテナ線条２及び第３のアンテナ線条３を接続することが指向性向上の点から好ましいが、給電点７に直接に第１のアンテナ線条１、第２のアンテナ線条２及び第３のアンテナ線条３を接続してもよい。ここで、接続線条６は図１における、給電点７から直接水平方向に伸長されている線条である。
【００１０】
後部サイド窓ガラス板８の周囲から中心に向かって、第１のアンテナ線条１、第２のアンテナ線条２、第３のアンテナ線条３の順に後部サイド窓ガラス板８に設けられている。また、第１のアンテナ線条１、第２のアンテナ線条２及び第３のアンテナ線条３は、それぞれが略平行となるように後部サイド窓ガラス板８に設けられている。
【００１１】
図１では、給電点７は、後部サイド窓ガラス板８の前部側の車体開口縁９近傍に設けられており、第１のアンテナ線条１の開放端は、給電点７近傍まで伸長されている。また、第２のアンテナ線条２の開放端は、後部サイド窓ガラス板８の上側の車体開口縁９近傍まで伸長されている。また、第３のアンテナ線条３の開放端は、後部サイド窓ガラス板８の下側の車体開口縁９近傍まで伸長されている。
【００１２】
給電点７から伸長される接続線条６に一端を接続している第４のアンテナ線条４が、車体開口縁９に沿って反時計回り方向に伸長されて、後部サイド窓ガラス板８に設けられている。このように給電点７から伸長される接続線条６に、第４のアンテナ線条４を接続することが指向性向上の点から好ましいが、給電点７に直接に第４のアンテナ線条４を接続してもよい。また、図１では、第４のアンテナ線条４は、第２のアンテナ線条２の開放端より後部サイド窓ガラス板８の中心に近い領域まで伸長されている。
【００１３】
第１のアンテナ線条１と第４のアンテナ線条４とが略平行に近づいている場合、この略平行に近づいている部分の少なくとも１００ｍｍの長さの両者の間隔については、２６ｍｍ以上とする。できるだけ容量結合させずに指向性を向上させるためである。
【００１４】
第２のアンテナ線条２と第４のアンテナ線条４とが略平行に近づいている場合（図１ではＬ1により示した近傍の部分）、この略平行に近づいている部分の少なくとも１００ｍｍの長さの両者の間隔（図１ではＬ2）については、２６ｍｍ以上とする。できるだけ容量結合させずに指向性を向上させるためである。
【００１５】
アンテナ線条１、２の長さは、ＦＭ放送帯の中心周波数の波長をλM とするとき、０．３λM ×Ｋ〜０．９λM ×ＫとすることがＦＭ放送帯の感度向上の点で好ましい。なお、Ｋはガラス短縮率であり、通常０．６４である。また、第１のアンテナ線条１と第２のアンテナ線条２とは、異なる長さとすることが好ましい。広帯域化のためである。
【００１６】
アンテナ線条３、４の長さは、０．１５λM ×Ｋ〜０．４λM ×ＫとすることがＦＭ放送帯の感度向上の点で好ましい。無給電線条であるダミー線条５は美感を向上させるために必要に応じて設けられるものである。なお、図１は車外から見たパターンであるが、車内から見て図１のパターンとなるものであってもよい。
【００１７】
図５は図１とは別の実施例の構成図であり、テレビ受信用アンテナ線条１６及びその給電点１７と、本発明の自動車用サイド窓ガラスアンテナとを同一の後部サイド窓ガラス板８とを設けている。このように本発明の自動車用サイド窓ガラスアンテナをテレビ受信用アンテナ線条と同一のサイド窓ガラス板に設けても、本発明の自動車用サイド窓ガラスアンテナは優れた指向性、感度特性を失わない。
【００１８】
なお、本発明のガラスアンテナを前部サイド窓ガラス板に設けてもよい。また、本発明のガラスアンテナを両側のサイド窓ガラス板に設け、両ガラスアンテナ間でダイバーシティ受信を行うことが指向性向上のために好ましい。
