PURPOSE: To improve the reliability at a low cost by providing a connection terminal connecting to an inductor forming a low pass filter sending a reception signal at an AM band from a sub antenna to a main antenna side at an AM/FM band.
CONSTITUTION: The antenna system is provided with an antenna 3 (main antenna), a defogging heater wire 5 (sub antenna) a feeding point 3a formed to one terminal of the antenna 3, a feeding point 4a formed to one terminal of a bus bar 4 connecting to the defogging heater wire 5, and a connection terminal 6 connecting to one terminal of an inductor 8 connecting to the feeding point 3a, and a window glass 2 with antenna with a window glass 2a to which a connection terminal 7 connecting to the feeding point 4a and to the other terminal of the inductor 8 is connected.
