Abstract
(EN) Provided is an antenna which can be arranged even on the front window glass while ensuring required sensitivity with a simple pattern.  The glass antenna is equipped with a core wire side element and a ground side element, wherein the core wire side element extends in a predetermined direction from a feeding terminal on the core wire side, the ground side element consists of a first element connected with a feeding terminal on the ground side and extending in parallel with the core wire side element and a second element connected with the feeding terminal on the ground side and extending in parallel with the first element.  The glass antenna is characterized in that the first element and a body flange are coupled capacitively by bringing the first element close to the body flange.
(FR) La présente invention concerne une antenne qui peut être placée sur un pare-brise avant, tout en bénéficiant de la sensibilité nécessaire, avec un motif simple. L'antenne de pare-brise comprend un élément situé du côté d'un câble principal et un élément situé du côté d'un branchement de mise à la masse. L'élément situé du côté d'un câble principal s'étend dans une direction prédéterminée à partir d'une borne d'alimentation située du côté du câble principal. L'élément situé du côté du branchement de mise à la masse comprend un premier élément qui est relié à une borne d'alimentation située du côté du branchement de mise à la masse et qui se prolonge parallèlement à l'élément situé du côté d'un câble principal ; il comprend également un second élément qui est relié à la cosse d'alimentation située du côté du branchement de mise à la masse et qui se prolonge parallèlement au premier élément. L'antenne de pare-brise est caractérisée en ce que le premier élément et une bride de corps sont couplés de façon capacitive lorsque le premier élément est amené à se rapprocher de la bride de corps.
(JA) 簡素なパターンで必要な感度を確保し、前部窓ガラスにも配設可能なアンテナを提供し、芯線側エレメントと接地側エレメントとを備えるガラスアンテナであって、前記芯線側エレメントは、芯線側給電端子から所定の方向に延伸され、前記接地側エレメントは、接地側給電端子に接続され、前記芯線側エレメントと並行に延伸される第1エレメントと、前記接地側給電端子に接続され、前記第1エレメントと並行に延伸される第2エレメントと、を備え、前記第1エレメントをボディフランジに近接させることによって、前記第1エレメントとボディフランジとを容量結合させたことを特徴とする。
