Grounded colocated antennas for wideband vector sensor applications

Abstract

In this communication, a wideband vector sensor for embedded applications is proposed. This original sensor is composed of two orthogonal and colocated semi-circular arrays of Vivaldi antennas mounted over a ground plane. Stable radiation patterns of two wideband magnetic dipoles and one wideband electric dipole are obtained from full-wave electromagnetic simulations over a 1.69:1 impedance bandwidth with an original control of the excitation.
