摘要：在時(shí)域用有限差分時(shí)域（FDTD）法研究超寬帶短徑傳播脈沖信號(hào)從寬帶圓錐單極天線通過(guò)鋼筋混凝土墻的建筑物所生成的數(shù)值。結(jié)果表明，鋼筋混凝土墻影響兩個(gè)發(fā)射天線的脈沖信號(hào)和散射濾波的波形。

Abstract ¬ The short path propagation of an UWB pulse generated numerically from a wideband conical monopole antenna through reinforced concrete wall of buildings has been studied in the time-domain using the finite-difference time-domain (FDTD) method. Results demonstrated the effects of both filtering of transmitting antenna and scattering of the reinforced concrete wall on pulse signal waveform.
I. INTRODUCTION
Ultra-wideband (UWB) communication becomes an interesting technology when the Federal Communications Commission (FCC) announced the unlicensed usage of spectra from 3.1 to 10.6 GHz under certain emission restrictions. The characterization of an UWB communication channel strongly depends on the electromagnetic characteristics of the environment in which it operates. In the environments of the indoor short path propagation of UWB signals inside a room, the UWB pulse propagation is dominated by man-made building walls and other obstacles. As a result, the pulse signal waveform, when reaching receiving antenna after ......
