摘要：
A novel dual-band decoupling and matching technique for asymmetric two-element antenna arrays is proposed. Decoupling and matching at two widely separated frequencies is accomplished by using a two-layer (level) network approach. Unlike previous works, analytical solution is readily available and prematching of the radiating elements is no longer required. Simulation and experimental results show that the proposed method can offer improved port isolation and input return loss, enhanced efficiency, and increased radiation pattern diversity in both frequency bands.
