A dual band miniaturised Artificial Magnetic Conductor design methodology

A design methodology to reduce inter unit cell mutual coupling in a miniaturized dual band Artificial Magnetic Conductor (AMC) is described. The AMC features miniaturization using lumped component loading and flexible dual band design with minimum mutual coupling between subunit AMC cells. The paper describes the advantages and disadvantages of four methods of designing a multiband AMC in terms of the minimum difference between the resonant frequencies of the two frequency bands.
