摘要：This paper concentrates on design, modeling, simulation and performance analysis of a Microstrip Line Quarter Wave Transformer-fed 4x4 Circular Patch phased array. The substrate material RTDuorid5880 used for this has thickness of 1.588mm and relative permittivity (εr) is 2.2. The design frequency is 2GHz and VSWR ≤ 2. The proposed 4x4 Circular Patch phased array is modeled and simulated by using ANSOFT HFSS 15.0. The gain of this array is 16.963 dB with return loss of -24.91dB. The phased array is steered for 100, 200, 300, 420 and 450 with a bandwidth of 31.9 MHz. This proposed Phased array is very useful for L band airborne applications such as satellite navigation, mobile wireless communication, radar and telemetry, tracking, and command (TTC) for mini satellites.
