In this paper, a 4x4 half-wavelength open Dipole multi-input multi-output (MIMO) measurements campaign at a frequency of 5.2 GHz is presented. Channel transfer function of the system is measured within 400MHz for different antenna polarization and displacement. Channel capacity, Correlation Coefficient, Ricean K-factor, as well as the channel delay spread are investigated in order to estimate the performance of a real MIMO dipole in an indoor environment. It is observed that with a fixed SNR, the capacities of VV and HV configuration increases with distance whereas HH and VH decreases with distance. Furthermore, it was realized that a set of Dipole elements is more efficient in the LOS as opposed to the NLOS.
