Abstract

An ultra wideband phased array antenna element in the frequency range of 5:1 and with the scan angle from -60° to 60° is designed in this paper. The Wide Angel Impedance Matching (WAIM) layer has a low profile as compared to the WAIM Layer presented in Finite Antenna Arrays and FSS. A hyperbolic balun is adopted to connect the printed planar dipole to the SMA connector, which is placed on the back of the ground plane. Simulation results of the designed phased array antenna show that the active VSWR of the element is less than 2.5 over an ultra-wideband of 5:1.
