This paper presents an experimental power angle profile measurement procedure, as well as theoretical capacity results of a single-input-multiple-output (SIMO) system which operates in the millimeter wave band and especially at 60 GHz. Power angle profiles (PAPs) were measured in different indoor locations while detailed angle-of-arrival (AoA) shape factors describing the spatial properties of the millimeter wave channel were derived. The measurement results were related to the sitespecific environments and showed correlation between the propagation environments and the multipath channel structure. The 10% outage capacity was found theoretically between 5.7 and 6.2 b/s/Hz for a 1
