| Zusammenfassung: | 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. |
