UHF無線電波在大樓中不同樓層間之傳播模式與量測

Abstract

在本論文中, 吾人發展出在大樓不同樓層間之無線電波理論傳播模式, 該 模式乃根據電磁波之反射, 穿透理論並結合射線理論而成. 另一方面並完 成在上述環境傳播之場強量測工作. 吾人發現地板, 橫樑及接收天線附近 之測強等結構特徵均會影響電波之樓層穿透損失. 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.
