Using directive antennas to reduce multipath fading in indoor PCN systems

Abstract

There is a growing need for indoor wireless PCN systems to provide high speed digital transmission between computer terminals and peripherals. Millimeter-waves were selected to implement this new system application, because of the capability to allow easy frequency re-use and the development of MMIC technology. This paper focuses on the characteristics of the MM-waves propagation with particular emphasis on the utilization of antenna directivity to combat multipath fading. Experimental results were conducted at 37.2 GHz under line-of-sight conditions. CW recordings are analyzed in terms of small-scale fading and path loss.
