Windowpane antenna apparatus for use in vehicles

摘要

A windowpane antenna apparatus for use in a vehicle according to the present invention, includes a plurality of conductive strips (14) arranged in a windowpane (2) of the vehicle so as to have a predetermined pattern, function designation switches (31s to 34s) turned on to transmit/receive predetermined waves, an arithmetic unit (26) for performing an arithmetic operation of obtaining a combination of the plurality of conductive strips (14) in order to form a desired antenna having antenna characteristics matching a function designated by the function designation switches (31s to 34s), and a selective connecting switch (21) for selecting one or some of the conductive strips (14) based on the combination of the conductive strips (14) obtained by the arithmetic unit (26) and connecting the selected some of the conductive strips (14) to form the desired antenna.
