This paper describes the design of a dual band Artificial Magnetic Conductor (AMC) with the use of lumped reactive components. The AMC comprises of a single layer of metallic patches, which have unit cells with capacitors between the patches. Dual band performance is achieved by having two different capacitors on alternating unit cells. The performance of the AMC is evaluated using simulations in CST microwave studio. The impact of the values of the capacitances in the AMC is assessed, with respect to frequency band separation. The AMC is designed to operate at 430MHz and 900MHz.
