Abstract: The apparatus for receiving a wireless signal with anti-jamming includes: a wireless signal receiving unit receiving a wireless signal and including at least one antenna; and a jamming signal blocking unit disposed in front of the wireless signal receiving unit to block a jamming signal input from at least one direction and having a size or an interval from the wireless signal receiving unit determined according to at least one of an antenna pattern of the wireless signal receiving unit, a direction in which the jamming signal is input, and a level of the jamming signal. According to an exemplary embodiment of the present invention, it is possible to smoothly receive a targeted signal while blocking the jamming signal under the environment in which a general signal and the jamming signal coexist.
