In this study, a feasible decoupling method is used for a binary-element closely spaced dual-band antenna array. The decoupling setup is used for array antenna element isolation. Decoupling and matching at two widely separated frequencies are accomplished by using a two-layer (level) network approach. Moreover, impedance matching is built into the decoupling network. The antenna array consists of two elements and works in dual-band (4.9-5.4 GHz and 2.2-3.1 GHz). This is considering that the elements of the antenna arrays are strongly coupled. A decoupling network is taken into account between the array elements and each element port. Thus the mutual coupling between the array elements is reduced well. It should be noted that other decupling methods cannot isolate and match the impedance simultaneously in the two bands. This technique has been applied to the desired array. The proposed structure is simulated with High-Frequency Structure Simulator (HFSS) software.
