“…Only the E-plane orientation field was measured. This explains the difference between measured channel gains for same measured distances since antenna elements oriented in the E-plane orientation are more strongly coupled than others [7].…”

Abstract-In this paper we consider time-division-duplex (TDD) reciprocity calibration of a massive MIMO system. The calibration of a massive MIMO system can be done entirely at the base station (BS) side by sounding the BS antennas oneby-one while receiving with the other BS antennas. With an M antenna BS, this generates M (M − 1) signals that can be used for calibration purposes. In this paper we study several least-squares (LS) based estimators, differing in the number of received signals that are being used. We compare the performance of the estimators, and we conclude that is possible to accurately calibrate an entire BS antenna array using the mutual coupling between antennas as the main propagation mechanism.

“…The magnitude of the S2\ parameter, both in E-and H-plane, is shown as a function of spacing between patch edges. For comparison, the measured results of planar case are also given [12]. It can be seen that the coupling is weaker for spherical case in comparison to the planar one, especially in H-plane.…”

“…Different channel magnitudes for equidistant antennas occur due to the relative orientation of the respective antenna pair with respect to the measured E-field polarization. In general, antenna elements placed in the same orientation as the measured E-field polarization couple stronger than others [8]. A linear least square fit has been performed to model the coupling magnitude as a function of antenna distance.…”
