The Improvement of Array Antenna Performance with the Implementation of an Artificial Magnetic Conductor (AMC) Ground Plane and in-Phase Superstrate
In this paper, the authors discuss performance improvement with the integration of an Artificial Magnetic Conductor (AMC) into array antennas. An AMC with Defected Ground Structure (DGS) was designed to construct the AMC ground plane and in-phase superstrate. The two distinguishable structures were integrated into an array antenna, which serves as a reference antenna at 5.8GHz. The impedance BandWidth (BW) of the reference antenna significantly improved to 287% when integrated with an AMC ground plane and with 37% reduced size.
