To achieve the main objective of this research project, the performance of MIMO antennas in these specified frequency bands was evaluated using the simulator. The simulator was used to model and simulate the MIMO antenna for smartphones, where different antenna configurations and designs were considered in terms of gain, directivity, efficiency, scattering parameters, and radiation pattern. The proposed antenna was designed on a 1.5 mm thick FR-4 substrate, with a dielectric permittivity of \ ε_r= 4,3, which consists of a copper coating on both sides of the foil. The MIMO antenna consists of a grouping of antennas placed symmetrically on both frames molded to the shape of the traditional smartphone; each structure is organized into four antennas of small size cast in mirror form if we take the first two antennas placed on the shelf with reference. The antenna array is placed in the same configuration as the other frame that makes up the mobile housing. The results of the electromagnetic simulator CST Studio Suite prove that the proposed antenna complies with the expected operating parameters. The adaptation for both frequencies exceed -15 dB for the reflection coefficient and -20 dB for the mutual coupling generated by the proximity in which the antenna is placed by using decoupling structures that allow each antenna to work more isolated about the others. |
