Disclosed is an antenna system including a glass antenna that is disposed in window glass that is installed in a window opening that is formed in a metal body of a vehicle, wherein the glass antenna is to receive a radio wave in a MF band or in a LF band; an in-vehicle antenna that is disposed at an inner side of the vehicle compared to the metal body of the vehicle, wherein the in-vehicle antenna is positioned in a vicinity of the glass antenna; and a canceler to cancel a noise signal of the in-vehicle antenna in a received signal of the glass antenna.

Antenna system

An antenna system includes a first antenna to receive a broadcast wave in a predetermined frequency band; a second antenna to receive noise from a noise source; and a canceler to cancel a noise signal received by the second antenna from a received signal received by the first antenna, wherein a radio wave of the broadcast wave in the predetermined frequency band equally reaches the first antenna and the second antenna, wherein reception gain for the predetermined frequency band received by the second antenna is lower than reception gain for the predetermined frequency band received by the first antenna, and wherein an output of the noise received by the first antenna is adjusted to be equal to an output of the noise received by the second antenna.

An electrically connecting structure includes a glass plate, a feeding part formed on the glass plate, a terminal having a base part opposing the glass plate, an adhesive adhering the glass plate and the terminal, and a conductive rubber arranged between the feeding part and the base part. The adhesive is a thermosetting adhesive that once softens when heated and thereafter cures, and is arranged to surround a periphery of the conductive rubber. The feeding part and the base part have electrical continuity via the conductive rubber.
