A novel 3D antenna for LTE MIMO systems

Two low-profile and compact 3D antennas operating at LTE, GSM and UMTS frequency bands (790-2690 MHz) are here numerically analyzed for a vehicular MIMO system. After an analysis of the single element performance, two identical 3D antennas are considered. A preliminary numerical analysis on the effect of geometrical parameters such as inter-element distance and reciprocal orientation have been discussed to improve the two-antenna system performance in terms of impedance matching, isolation and envelope correlation coefficient.
