Abstract
A novel and compact triple-band two-element Multiple Input Multiple Output (MIMO) antenna array is designed to provide simultaneous communications for uplink and downlink which covers GSM, LTE, and sub-6 base station applications. The proposed MIMO system is a configuration of four triple-band two-element arrays in which two are used for uplink and the other two for downlink. This compact structure with separate antennas for uplink and downlink provides simultaneous communication. For this proposed structure, the parameters like impedance bandwidth, efficiency, gain and cross polarization aspects are presented for all the three specified bands. To achieve good isolation uplink and downlink arrays are placed orthogonal to each other. Further, to enhance the isolation a defected ground is incorporated for the antenna array structure, and isolation strips are provided between uplink and downlink arrays. In addition, for the proposed structure diversity performance with Envelope Correlation Coefficient (ECC) and diversity gains are also calculated. The simulated and measured results are in acceptable correlation.
