Abstract

Este trabajo trata de un arreglo de antenas MIMO (multiple-input-multiple-output) que opera en la banda de 2.6 GHz, una banda de Long Term Evolution (LTE), para sistemas de comunicaciones móviles inalámbricas 4G. El arreglo de antenas consiste de 4 antenas compactas tipo patch sobre un substrato dieléctrico (PCB) de 125 mm x 62.5 mm x 1.27 mm. Modificaciones del plano de tierra (GND) junto con la ubicación sistemática y orientación de cada antena en la cara posterior al plano de tierra del PCB (Printed Circuit Board) juegan un rol muy importante en la reducción sustancial del acoplamiento mutuo, esto generalmente afecta el desempeño de los arreglos MIMO.
