碩士 === 國立交通大學 === 電信工程研究所 === 101 === In this research work, we analyze the channel capacity in indoor 60GHz environment with the structure of dual-polarized patch antenna planar array. In indoor 60GHz environment, the dual-polarized antenna not only solves the dead zone problem of the patch antenna but also provides the low spatial correlations to enjoy the advantages of MIMO system. We also discuss how do we derive the larger channel capacity based on the structure of dualpolarized antenna planar array. We show that beamforming is suitable for the low transmit power, and multiplexing is suitable for the high transmit power. The boundary of transmit power is -6.3 dBm for existing the LOS path and using the face-to-face theoretically transmitter and receiver antennas which are separated by the distance of two meters. When receiver locates in the dead zone of one transmitted polarization, there are some benefits by focusing the power on the other transmitted polarization for the low transmit power. Moreover, we derive a not only simple but also approximate Kronecker model by the ray-tracing channel model.
