Antenna array

摘要

The present application relates to an antenna array that comprises a plurality of antenna elements and a plurality of amplifiers feeding the plurality of antenna elements. A first group of the plurality of antenna elements is arranged in a first column and a second group of the antenna elements is arranged in a second column. A first amplifier of the plurality of amplifiers has a first power rating and a second amplifier of the plurality of amplifiers has a second power rating, the first power rating being different than the second power rating. The first column is arranged symmetrical to the second column about an axis. Amplifiers feeding the first column have a substantially similar power rating to corresponding amplifiers feeding the second column.

1. An antenna array comprising a plurality of antenna elements and a plurality of amplifiers having power ratings and feeding the plurality of antenna elements, wherein a first group of the plurality of antenna elements is arranged in a rectilinear planar array of a first column of the antenna array and a second group of the plurality of antenna elements is arranged in a rectilinear planar array of a second column of the antenna array, wherein a first amplifier of the plurality of amplifiers has a first power rating and a second amplifier of the plurality of amplifiers has a second power rating, the first power rating being different than the second power rating, wherein the first column of the plurality of antenna elements is arranged symmetrical to the second column of the plurality of antenna elements about a rectilinear parallel axis, and wherein the amplifiers feeding the first column of the plurality of antenna elements have a substantially similar power rating to the corresponding amplifiers feeding the parallel second column of the symmetrically corresponding one of the plurality of antenna elements, the antenna array further comprising a plurality of high power transceivers, the high power transceivers comprising one antenna element of said plurality of antenna elements and one amplifier of said plurality of amplifiers, wherein the amplifiers feeding the first column of the plurality of antenna elements and the amplifiers feeding the second column of the plurality of antenna elements are digitally linearized to enable tracking in amplitude and phase of the high power transceivers.
