Abstract	The mechanical-electromagnetic-field-coupling-model (MEFCM) is widely used in analysing the effect of structural deformation on radiation pattern of reflector antennas. Due to lack a closed-form optical path difference expression for shaped reflector antennas, the MEFCM cannot be;directly applied. For this shortcoming, in order to apply the coupling model into shaped dual-reflector antennas, we proposed a new shaped surface description approach based on standard discrete parabola set. By employing this approach, the MEFCM can be applied to analyse the radiation pattern;of shaped dual-reflector antenna with different types of structural deformation. Application on a 25 m shaped Cassegrain antenna shows the effectiveness of the proposed approach for the pattern analysis of shaped dual-reflector antennas.
