In this paper, we propose a solution to resolve link blockage problem in 60 GHz WPANs. Line-of-Sight (LOS) link is easily blocked by a moving person, which is concerned as one of the severe problems in 60 GHz systems. Beamforming is a feasible technique to resolve link blockage by switching the beam path from LOS link to a Non-LOS (NLOS) link. We propose and evaluate two kinds of Beam Switching (BS)...
Abstract-The paper proposes a codebook design to support beamforming mechanism in a wide band millimeter-wave 60 GHz wireless personal area networks (60 GHz WPANs) in a realistic millimeter-wave environment. The codebooks are designed symmetrically in order to mitigate the possible beam shift due to the large differences of wave lengthes at different sub-bands of a wide band communication system....
Beam steering antenna is expected in 60 GHz wireless communication system to improve the signal to noise ratio and obtain high gain with wide cover range for high speed WPAN application. In this paper, patch antenna arrays with planar topology are investigated by synthesizing the network losses and devices such as phase shifters. The investigation results can provide a valuable guide line for the...
