摘要：

Electromagnetic band gap (EBG) structures are usually realized by periodic arrangement of dielectric materials. These periodic structures can help in the reduction of mutual coupling in array antennas. In this paper a new arrangement of EBG structures is presented for reducing mutual coupling between patch antenna MIMO arrays. The patch antennas operate at 5.35GHz which is defined for wireless application. Here 2 × 5 EBG structures are used to reduce mutual coupling more than 20 dB. The total size of the antenna is 36mm × 68mm × 1.6 mm. So it is more compact in than pervious research. Experimental results of return loss and antenna pattern have been presented for 5.4GHz and compared with HFSS simulation results. Also the EBG structures have been designed with numerical modeling and dispersion diagram. New EBG model is compared with conventional EBG model, and equivalent circuit model is given for new structure. © 2014, Electromagnetics Academy. All rights reserved.
