Design and optimization of metamaterial-based highly-isolated MIMO antenna with high gain and beam tilting ability for 5G millimeter wave applications This paper presents a wideband multiple-input multiple-output (MIMO) antenna with high gain and isolation, as well as beam tilting capability, for 5G...
LTE-A uses multiple input, multiple output (MIMO) antenna technologies similar to that used in the IEEE 802.11n wireless local area network standard. MIMO and OFDM enable a highersignal-to-noise ratioat the receiver, providing improved wireless network coverage and throughput, especially in dense ...
