Abstract：
Design a derived antenna pattern has important application in communication and radar systems. This presentation discusses antenna pattern design using Minimax algorithm.
If antenna weight is a general complex numeric, antenna pattern design is relative straight forward. If there is a hardware coronial, antenna weight can only adjust phase, the performance surface is a multimode function in multi-dimensional space. Propose antenna pattern depends on initial phase. If the initial phase is not chosen properly, it will not be able to get the good antenna pattern.
