To make it possible to receive radio waves in a plurality of bands regardless of whether an element is folded back.SOLUTION: A vehicle glass antenna, provided on a window glass attached to a window frame of a vehicle body, capable of receiving vertically polarized waves in a first frequency band and horizontally polarized waves in a second frequency band, includes: a power supply electrode for power supply and a ground electrode for ground, provided along an end side of the window frame; a first element extending from the power supply electrode in a direction toward the end side or in a direction opposite to the end side; a second element extending from the first element along the end side in a direction opposite to the ground electrode side; and a ground element extending along the end side in a direction opposite to the side of the power supply electrode from the ground electrode. A length of the first element is shorter than a length of the second element.SELECTED DRAWING: Figure 1
【課題】エレメントの折り返しの有無にかかわらず、複数の帯域の電波を受信できること。【解決手段】車体の窓枠に取り付けられる窓ガラスに設けられ、第1の周波数帯の垂直偏波と第2の周波数帯の水平偏波を受信可能な車両用ガラスアンテナであって、前記窓枠の端辺に沿って設けられる、給電用の給電電極及びアース用のアース電極と、前記給電電極から前記端辺の側の方向または前記端辺の側とは反対側の方向に延伸する第1のエレメントと、前記第1のエレメントから前記アース電極の側とは反対側の方向に前記端辺に沿って延伸する第2のエレメントと、前記アース電極から前記給電電極の側とは反対側の方向に前記端辺に沿って延伸するアースエレメントとを有し、前記第1のエレメントの長さは、前記第2のエレメントの長さよりも短い、車両用ガラスアンテナ。【選択図】図1
