Title:
ANTENNA SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/093490
Kind Code:
A1
Abstract:
An antenna system comprises: a first antenna that has a first antenna conductor and a first feeding point and that receives broadcast waves of a predetermined frequency band; a second antenna that has a second antenna conductor and a second feeding point and that receives noise from a noise source; and a cancel device that cancels, from the received signals acquired by the first antenna, the noise signals acquired by the second antenna. The antenna system is adjusted such that: the radio waves of the broadcast waves of the predetermined frequency band equally reach the first and second antennas; the reception gain of the predetermined frequency band received by the second antenna is lower than the reception gain of the predetermined frequency band received by the first antenna; and the output of the noise received by the first antenna is equal to the output of the noise received by the second antenna.
