Design of MIMO antenna with decoupling network for LTE mobile application
A MIMO antenna with decoupling network for LTE mobile application is proposed. To improve the isolation between the two radiating elements of MIMO antenna, decoupling network is added. The decoupling network consists of two sections of transmission line, a shunt reactive component and quarter-wavelength jointed shorting structure. The isolation is improved by approximately 25 dB at the center frequency. The fabricated MIMO antenna satisfies a 6 dB return loss requirement and an envelope correlation coefficient below 0.4 over the LTE band 13 from 746 MHz to 787 MHz.
