Eigenmode Analysis of an AMC Ground Plane for Wideband High-Gain Antennas

When trying to enlarge the bandwidth of antennas based on artificial magnetic conductors (AMC), the radiation pattern tends to split at broadside. A rectangular non-periodic design has been proposed by Mateos, R.M. (2006) to overcome this problem. An eigenmode analysis based on the method-of-moments (MoM) technique is performed to study the wave modes… (More)
