Wide-Angle Impedance Matching of Phased-Array Antenna Using Overlapped Subarrays

摘要：

　　For phased array antennas, the active impedance of the radiating elements changes considerably with scan angle.Therefore it is ordinarily possible to match the active impedance at only one scan angle.In this paper, a microstrip patch phased array using overlapped subarrays is designed and simulated.It is found that by using overlapped subarrays good impedance matching over a wide range of scan angle can be achieved.Simulated results show that the investigated phased array has much better scan performance compared with conventional microstrip patch phased arrays.
