Abstract

Multi-input Multi-output (MIMO) antenna with improved isolation using radio frequency choke (RFC) is proposed. By using RFC, the RF signal was suppressed at the desired frequency band, to improve the isolation between the two radiating elements. The isolation between the two radiating elements is improved by approximately 20 dB at the center frequency. The fabricated antenna has a VSWR below 3 and an envelope correlation coefficient below 0.4 in the long term evolution (LTE) band 13 from 746 MHz to 787 MHz.
