The multi-field coupling models of microwave reflector antennas

plate slot-array antennas and active phased array antennas have been developed in this communication

based on which the solution strategies and methods are presented to determine efficiently the effects of systematic errors

random errors and temperature etc.on the electrical performance of antennas.Some experiments are performed to validate these models and methodologies.Finally

a multidisciplinary optimization design model based on the muli-field coupling theory is derived with employing a common design vector

which can greatly reduce the repetitive works and ease the debugging of products.
