LOADING STRUCTURE OF ON-VEHICLE INTEGRATED ANTENNA DEVICE

摘要

PPROBLEM TO BE SOLVED: To attain the standardization of the loading mode of a vehicle indoor short range radio communication antenna while the antenna performance of the vehicle indoor short range radio communication antenna is assured appropriately and to avoid beforehand the increase of a developing man hour or a design man hour and a cost rise. PSOLUTION: A BT communication antenna 3 having the directivity in the direction of a zenith is horizontally united with an antenna 2 for a GPS in the directivity in the direction of the zenith, and is carried under an instrument panel so that it may have the directivity in the direction of the compartment of the vehicle horizontally with the antenna 3 for the GPS. While an influence by approaching a metal is avoided and the antenna performance of the antenna 3 for the BT communication can be assured appropriately, and standardization can be attained about the mode in which the loading mode of the antenna 3 for the BT communication is dependent on the loading mode of the antenna 2 for the GPS, and the antenna 3 for the BT communication is carried.
