Temporal-Angular channel sounding measurements of an indoor millimeter wave channel (60 GHz) is analyzed to determine whether ray arrivals at the receiver form clusters in the two-dimensional time-angle space. The channel behavior for directional antennas (with various 3dB beamwidths) at the transmitter is discussed and geometric interpretation of the results is provided. Additionally, observation of energy distribution among the clusters for directional antennas with various beamwidths is presented.
