“…Then, the directional CIRs and PAPs have been computed weighting the intensity of the rays with the 3D directional radiation patterns for the different antenna orientations. Due to the limited information available about the antenna radiation characteristics (radiation patterns available only on 2 planes), interpolation of the E-and Hplane antenna diagrams [33], [34] has been applied to extract the required 3D patterns.…”

“…Probably, the interference is much more dependent on minor, multiple-bounce paths and secondary antenna pattern lobes that are not accurately described in RT simulation. In particular, the RT antenna is described using 3D pattern reconstruction [33], [34] from 2D radiation diagrams, and therefore secondary, off-axis lobes are subject to interpolation errors. The larger interference consequently affect the SINR prediction, thus often preventing RT from identifying the really optimal beam steering directions.…”

This study concerns the evaluation of beamforming techniques in multi-user indoor environment at the mm-wave frequency band of 70 GHz using both measurements and ray tracing simulations carried out in a furnished small-office environment. The goal of the work is twofold: (i) to evaluate ray tracing as a reliable directional channel model for beamforming assessment and for real-time assistance in the beam-searching phase, (ii) to evaluate simple beamforming schemes as means to enforce spatial division in a small-indoor environment. Results suggest that the considered ray tracing model can be reliable enough to reproduce the general performance trends of different beamforming schemes and to assist the beam-searching phase, therefore potentially reducing the related time delay and computational overhead.

“…Traditional test methods are incompetent to meet the demand of mass production test. Methods have been proposed to improve the testing efficiency by reducing the number of profiles tested and the number of sampling points on individual profile [10][11][12]. However, the testing time is not significantly reduced, but the error introduced is quite large.…”

The testing requirements of the active phased array antennas are very different from those of traditional passive antennas, due to its beam steering capability. Usually, each beam profile of the active phased array needs a separate radiation pattern test, which makes the overall testing time extremely long. Thus the traditional antenna test method can no longer meet the efficiency and cost requirements of new active phased array antennas test. In this paper, a fast test method tailored for phased array antennas is proposed that offers significantly reduced testing time at the expense of slight sacrifice of the accuracy. Using the simulated element pattern in array and ideal port excitation, the beam profile in any direction can be predicted by testing only a certain beam profile. Through theoretical derivation and experiments, the effectiveness of the method is verified, and the testing efficiency of the phased array antenna is demonstrated to be improved by ten times or even more.

“…Recent progress [ 10 , 11 , 12 ] has been made based on experimental environment and focused on the fast measurement of a single antenna pattern in anechoic chambers or nonanechoic chambers. Some efficient methods, known as antenna pattern interpolation, are implemented to reconstruct the 3D pattern from 2D pattern, by reducing the number of pattern cuts or sampling points being measured [ 13 , 14 ]. The phase-shift measurement method is also introduced in [ 15 ] to accelerate the far-field pattern calculation.…”

The measurement of the phased array antenna (PAA) is completely different from the traditional antenna, due to its multi beam patterns. Usually, each beam pattern of the PAA needs a separate measurement, which makes the overall time extremely long. Thus, the traditional method can no longer meet the efficiency and cost requirements of new PAA measurement. In this paper, a pattern reconstruction method is proposed which significantly reduce the measurement time of multi-beam PAAs. With the known array element patterns (AEP) and theoretical weighted port excitation of the beams, any beam pattern can be predicted by measuring only a certain beam pattern, due to the element excitation coefficient (including the matching, mutual coupling, and manufacturing factors, etc.) of the specific PAA being calculated. The approach has low reconstruction error in term of beam pointing accuracy, side lobe, and co-polar and cross-polar patterns while being validated for large scanning range. Through theoretical derivation and experiments, the effectiveness of the method is verified, and the testing efficiency of the phased array antenna can be improved by 10 times or even more.
