Abstract: To analyze the effects of different antenna polarization on indoor ZigBee channel transmission characteristics,the paper constructed a deterministic model of a specific apartment based on ray tracing method.Then it utilized Wireless Insite to present a simulation analysis on the four kinds of antenna polarization (horizontal polarization,vertical polarization,left-hand polarization and right-hand polarization).At last,through comparatively analyzing the path loss,the received power and the delay spread channel parameters,we got some conclusions of great value,such as vertical polarization leads to the best received power,but has serious delay spread;left-hand polarization and right-hand polarization have lower path loss than linear polarization,but the received power is not ideal;the wooden doors and partition walls have little effect on the spread of ZigBee channel while the metal door will leads to a serious loss of transmission waves,and so on.
