Abstract

In this paper, the discussion concentrates on modelling, simulation and performance analysis of a Microstrip Line Quarter Wave Transformer-fed 8x8 Circular Patch phased array. The substrate material used for this has thickness of 1.588mm and relative permittivity (er) is 2.2. The design frequency is 2GHz and VSWR = 2. The proposed 4x4 Circular Patch phased array is modelled and simulated by using ANSOFT HFSS 15.0. The gain of this array is 24.639 dB, return loss of -16.2810dB and bandwidth is 327MHz. The phased array is steered for 100, 200, 300, 380 and 450. These types of phased arrays are very useful for airborne applications.
