ABSTRACTFor multiple‐input‐multiple‐output (MIMO) system a dual‐band dual‐polarized antenna is presented. The antenna which is presented in this thesis produces a linearly polarized and circularly polarized radiation fields. The measured return losses of −18.89 and −21.86 dB are achieved at 2.43 GHz and 3.22 GHz, respectively. In this the proposed antenna is designed and simulated using Ansoft HFSS Software. The result shows that the gain of the antenna has increased by 1.4dB and 1.2dB at 2.43 and 3.22 GHz, respectively by using the FSS. A compact dual‐band dual‐polarized antenna is achieved. The proposed antenna is fabricated and validated experimentally using VNA. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2699–2703, 2016
