Statistical Analysis of Huge-Scale Periodic Array Antenna Including Randomly Distributed Faulty Elements

On the huge-scale array antenna for SSPS (space solar power systems), the problem of faulty elements and effect of mutual coupling between array elements should be considered in practice. In this paper, the effect of faulty elements as well as mutual coupling on the performance of the huge-scale array antenna are analyzed by using the proposed IEM/LAC. The result shows that effect of faulty elements and mutual coupling on the actual gain of the huge-scale array antenna are significant. key words: Method of Moments (MoM), impedance extension method (IEM), local admittance compensation (LAC), array antenna
