摘要: | 在本论文中, 吾人发展出在大楼不同楼层间之无线电波理论传播模式, 该 模式乃根据电磁波之反射, 穿透理论并结合射线理论而成. 另一方面并完 成在上述环境传播之场强量测工作. 吾人发现地板, 横梁及接收天线附近 之测强等结构特征均会影响电波之楼层穿透损失. In this report, a general three-dimension theoretical model is developedto predict the path loss of UHF radio wave through floors in a building.The model based on the ray-tracing technique and electromagnetic theories of reflection, transmission and ray-fixed coordinate system. It is found that the floor, lateral beams and the walls around the receiver are the major construction features to affect the estimation of the penetration loss. |
