In this paper, a study for indoor channel modeling is presented for the millimeter frequency band, by using various configurations of multiple element antenna systems. A multi-ray model is proposed and verified through simulation process for capacity prediction of a high data rate wireless system. The proposed model utilizes the geometric characteristics of the environment, the angle of arrival and angle of departure of each one of the propagation paths, the antenna elements and their spacing.

... he results showed that the system capacity increases significantly if two or four elements are used at both terminal antennas instead of the basic SISO configuration. In order to accomplish major improvement in the data rates, a MIMO system at 60 GHz should operate within a range of 10 to 20 m in an indoor environment with the view of obtaining sufficient Signal to Noise Ratios.
