    Abstract
  • The electromagnetic performance of phased array antenna (PAA) is degraded because of the array plane structural error caused by manufacturing processing and assembly. It seriously restrict the realization of high performance of the phased array antenna. Therefore, by introducing the plane structural errors into the antenna pattern function as an additional phase factor, a coupled structural-electromagnetic model was developed, which described the effect on the performance of planar hexagonal phased array antenna with the plane structural errors. The direct influence relationship of the electromagnetic performances of antenna with the plane installation accuracy and planar tolerance was analyzed. The critical value of array plane structural error was given when meet antenna performance requirement. The analysis results provide a theoretical guidance for the engineer to set the tolerance in manufacturing antenna.
