Abstract: | In general, an accurate mutual coupling correlation is necessary for an array antenna to reach ideal sideiobe level. If the mutual coefficient matrix of an array antenna is perfectly known, one can completely compensate the effect of mutual coupling and realize the desired sidelobe level in theory. However, the mutual coefficient matrix obtained wherever by calculation on by measurement has a limited precision. In this paper, the requirements on the precision of matrix coefficient for compensation in low sidelobe array antenna are discussed. The relationship between mutual coefficient errors and the amplitude and phase errors of channels is derived. |
