Abstract: There is provided an antenna beam detection and monitoring apparatus which uses a beam intensity detection sheet with patterned coupling lines. The antenna beam detection apparatus according to an embodiment includes: a sheet which is disposed on an upper end of a beam radiation surface of an antenna and has a plurality of coupling lines formed therein to allow beams radiated from the antenna to be coupled thereto; and a plurality of detectors configured to measure intensities of beams coupled to the coupling lines, respectively, by using the beams radiated from the antenna. Accordingly, it is possible to monitor performance of an antenna in real time with a small-sized device and a low cost even when the antenna is operating.
