Abstract

Mutual coupling has a demonstrable impact on the embedded pattern of the focal plane array (FPA). Therefore, it is necessary to optimize the FPA complex weighting to achieve the antenna system maximum gain. A system level model based on a hybrid combination of an in-house developed PO tool, an EM tool (CST). It turns out that the mutual coupling effects on the embedded patterns of the FPA can be can be optimized through the application of a minimum least squares (LS) residual method. Subsequently, the geometry and pattern of the FPA can be further optimized to increase the efficiency of the reflector antenna system.
