Abstract A novel compact low profile MIMO antenna is designed and implemented with high isolation for the X band applications. Proposed MIMO geometry is incorporated with two monopoles which are excited by 50 Ω feed line. To enhance the isolation between inter-elements meander line structures are is identically placed. These meander line structures are reducing the mutual coupling up to 26 dB. In the proposed MIMO antenna two elements cover the entire frequency range between 7.4-11.8 GHz for the X band applications. Meander line structure is working as a decoupling network which improves the isolation considerably. The overall size of the MIMO antenna is 25 × 30 × 1 mm3, and it offers inter-element isolation of >26 dB, envelope correlation coefficient is less than 0.2, and directivity gain >9.99 over the resonating frequency range. The proposed MIMO antenna model is fabricated, and measurement results are verified with simulated results. The antenna shows the satisfactory gain of around 4.8 dB in entire frequency range. The antenna shows the satisfactory gain of around 4.5 dB in entire frequency range.

With the development of 5G, Internet of Things, and smart home technologies, miniaturized and compact multi-antenna systems and multiple-input multiple-output (MIMO) antenna arrays have attracted increasing attention. Reducing the coupling between antenna elements is essential to improving the performance of such MIMO antenna system. In this work, we proposed a graphene-assembled, as an alternative material rather than metal, film-based MIMO antenna array with high isolation for 5G application. The isolation of the antenna element is improved by a graphene assembly film (GAF) frequency selective surface and isolation strip. It is shown that the GAF antenna element operated at 3.5 GHz has the realized gain of 2.87 dBi. The addition of the decoupling structure improves the isolation of the MIMO antenna array to more than 10 dB and corrects the antenna radiation pattern and operating frequency. The isolation between antenna elements with an interval of 0.4λ is above 25 dB. All experimental results show that the GAF antenna and decoupling structure are efficient devices for 5G mobile communication.
