AXIAL RATIO COMPENSATION METHOD FOR ANTENNA ARRAY

원문 (중국어)

An axial ratio compensation method performed by an antenna system including an antenna array having antenna elements is provided. The axial ratio compensation method includes: receiving, by the antenna array, a first linearly polarized beam from a predetermined direction by enabling respective first ports of the antenna elements, so that the antenna array generates a first radio frequency (RF) signal; receiving, by the antenna array, a second linearly polarized beam from the predetermined direction by enabling respective second ports of the antenna elements, so that the antenna array generates a second RF signal, wherein the first linearly polarized beam and the second linearly polarized beam are substantially orthogonal; and compensating at least one of a phase difference and a magnitude difference between the first RF signal and the second RF signal to compensate an axial ratio of the antenna array at the predetermined direction.
