Abstract
An on-vehicle antenna system which offers a superior receiving performance, by suppressing reception of reflected/scattered waves coming from inside of the vehicle's cabin; these reflected/scattered waves being an adverse factor which deteriorates signal receiving performance of an antenna. The antenna system is installed at glass pane portion of a vehicle with direction () of the greatest radiation pattern () directed towards ahead () of the vehicle from boundary plane () containing power supply portion (), while direction () of the smallest radiation pattern () towards behind () of the vehicle. The above-configured antenna system can suppress those waves reflected/scattered in the vehicle cabin from being received; as the result, it demonstrates improved characteristics.
