A new ultra-wideband MIMO antenna based on metamaterials for 5G
An improved ultra-wideband low-coupling MIMO antenna based on a metamaterial periodic structure frequency-selective surface wide slot antenna is derived from the basic -shaped resonant ring.The antenna can be implemented without loading any parasitic branches low coupling and high gain, the relative bandwidth exceeds the international standard of ultra-wideband (20%),and at the same time uses metamaterials whose electromagnetic characteristics can be artificially changed as a medium,the element antennas are arranged in a 9 × 9 array and processed at 90° In order to achieve the goal of miniaturization,the structure is more compact The 37 GHz MIMO antenna with a structure size of 108 mm × 104 mm × 1 mm working in the 5G millimeter wave band is simulated.The results show that the peak gain of the unit antenna bandwidth is 10 dB,the impedance bandwidth is 21%, and the isolation is less than 20 dB. It meets the expected performance requirements of ultra-wideband, low coupling, miniaturization and other performances, and will have important applications in the area of 5G mobile communications.
