Ítem Diseño de una Antena LTE 7 MIMO para Uso en el Terminal MóvilRojas Sabogal, Juan Sebastián; Suárez Fajardo, Carlos ArturoThis paper presents the design of a MIMO antenna for applications in mobile phones in the band 4G LTE, from the study of various proposals related to the state of the art on this subject, by which he put forward a proposal optimized using simulators ANSYS electromagnetic such as HFSS and IE3D 15. The proposed solution consists of two elements, a broadband antenna with a single port, 34mm x 47mm dimensions, which operates in the range of 2-6GHz referred to a level of 6 dB return loss and an antenna MIMO 2x2 result integrating two antennas in a broadband single substrate 68 x 68mm, operating range 2-10GHz regarding a level 10dB return loss. After checking the design requirements outlined in the project objectives making prototypes we were made to then be validated by measurement of S parameters, gain and radiation pattern. This characterization of the prototypes was performed in the laboratory facility telecom University Francisco José de Caldas using specialized as are the vector network analyzer equipment, anechoic chamber and antennas Logarithmic Periodic reference. The project yields results in a MIMO antenna with features that allows it to be implemented in the mobile phone industry, particularly in mobile equipment. As well as a detailed analysis of the dimensions of the antenna parametric study providing valuable information to future designers to optimize the current design or possibly establish a strategy to raise future proposals.
