Title (EN) ON-VEHICLE ANTENNA DEVICE
(FR) DISPOSITIF D'ANTENNE EMBARQUÉ
(JA) 車載アンテナ装置
Abstract:
(EN) This on-vehicle antenna device to which a plurality of antenna elements are provided is provided with: a reception unit that receives a wireless signal via the antenna elements; and a switching unit that is interposed between the reception unit and the antennal elements and performs switching to one of the antenna elements to be connected to the reception unit, wherein the respective antenna elements are arranged such that the dipping direction based on the horizontally polarized wave directivity of one of the antenna elements is different from the dipping direction based on the horizontally polarized wave directivity of at least another one of the antenna elements.
(FR) L'invention concerne un dispositif d'antenne embarqué auquel sont fournis une pluralité d'éléments d'antenne qui est pourvu : d'une unité de réception qui reçoit un signal sans fil par l'intermédiaire des éléments d'antenne ; et d'une unité de commutation qui est interposée entre l'unité de réception et les éléments d'antenne et effectue une commutation vers un des éléments d'antenne à relier à l'unité de réception, les éléments d'antenne respectifs étant agencés de sorte que la direction d'immersion sur la base de la directivité d'onde polarisée horizontalement d'un des éléments d'antenne soit différente de la direction d'immersion sur la base de la directivité d'onde polarisée horizontalement d'au moins un autre des éléments d'antenne.
(JA) 複数のアンテナ素子が設けられた車載アンテナ装置であって、複数のアンテナ素子を介して無線信号を受信する受信部と、複数のアンテナ素子と受信部との間に介在し、複数のアンテナ素子の内、受信部に接続されるいずれかのアンテナ素子へ切替える切替部とを備え、複数のアンテナ素子の内、一のアンテナ素子の水平偏波指向性によるディップの方向は、少なくとも1つの他のアンテナ素子の水平偏波指向性によるディップの方向とは異ならせて、夫々のアンテナ素子が配置してある。
