4-Port Vector Antenna for MIMO Applications

A wideband 4-port vector antenna previously re-ported for radio-goniometry applications using four ports is investigated here for MIMO applications. Thank to the polarization diversity capabilities inherent to vector antennas, the MIMO performances are very good for wideband frequency operation.The main metrics that are generally used for MIMO antennas are reported. These characteristics enable the 3D-half-space angular coverage
