The realistic array antennas are inevitably susceptible to mechanical manufacturing errors, external loads and high thermal difference, which result in the unexpected notable degradation of electromagnetic performances with the corresponding element position error, seriously restrict the development of high-performance array antenna. The element position error include random error and systematic error,...
The analysis of electromagnetic performances of active phased array antennas with distorted plane errors is important to the engineering development of high-performance antennas. An coupled model is developed, which describes the effect on the performances of the errors caused by the bent and bowl shape distortion in the plane element positions. The application of the model to a plane array antenna...
