| 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. |
