2 . The broadcast receiving apparatus according to claim 1 , wherein a maximum distance between two unit antennas among the plurality of unit antennas is less than a half wavelength of the broadcast signal.

3 . The broadcast receiving apparatus according to claim 1 , wherein each receiving module of the plurality of receiving modules is configured to convert the broadcast signal into the first signal by shifting the broadcast signal received in the corresponding unit antenna from a high frequency band into an intermediate frequency band.

4 . The broadcast receiving apparatus according to claim 3 , wherein each receiving module of the plurality of the receiving module comprises a radio frequency integrated circuit (RFIC).

5 . The broadcast receiving apparatus according to claim 1 , wherein each the first signals comprises a broadcast signal component and the noise component, and
the filter is configured to acquire the broadcast signal components having relatively high correlation and remove the noise component having relatively low correlation by comparison between the first signals.

6 . The broadcast receiving apparatus according to claim 1 , wherein the filter comprises an adaptive filter.

7 . The broadcast receiving apparatus according to claim 1 , further comprising:
a second antenna group comprising at least one unit antenna and spaced apart from a first antenna group comprising the plurality of unit antennas; and a signal synthesizer configured to synthesize second signals corresponding to the first antenna group and the second antenna group into a third signal and output the third signal to the signal processor.

8 . The broadcast receiving apparatus according to claim 7 , wherein a minimum distance between the first antenna group and the second antenna group is longer than a half wavelength of the broadcast signal.

9 . The broadcast receiving apparatus according to claim 7 , wherein the first antenna group is located at a place where a receiving electric field is weaker than a receiving electric field of a place for the second antenna group.

10 . A broadcast receiving apparatus comprising:
a single antenna configured to receive a broadcast signal; a plurality of receiving modules configured to convert the broadcast signal branched and output from the single antenna into first signals; a filter configured to filter a noise component out of the first signals received from the plurality of receiving modules and synthesize the first signals into a second signal, and output the second signal; and a signal processor configured to perform a signal process for displaying an image based on the second signal output from the filter.
