Abstract:

The analysis of the influence of the distorted plane on the electromagnetic performance of the active phased array antenna (APAA) is of great significance to the research and development of the high-performance APAA. By introducing the plane random errors and deformations into the antenna pattern function as an additional phase factor, the coupled structuralelectromagnetic model is established of the relationship between the distorted plane and the electromagnetic performance of the planar rectangular APAA. The far field pattern of antenna with the deformation of array plane is studied by simulation. By the proposed method and conclusion, the antenna designers may set reasonable requirement on the tolerance in manufacturing antenna.
