摘要

研究了传统的单输入单输出(SISO)超宽带系统在链路两端的多元天线(MIMO: Multiple- input Multiple- output)扩展。从频域测量数据出发，分析了超宽带双锥天线阵列的互耦合特性和时域辐射方向图。在视距(LOS)和非视距(NLOS)环境下，通过测量无线电信道的信噪比(SNR)增益来评估MEA对超宽带通信的贡献。

Using multiple antennas in UWB communications

Extensions of traditional Single-Input Single-Output (SISO) UWB systems to Multiple Elements Antennas (MEA) at both ends of the links (MIMO: Multiple-Input Multiple-Output) are investigated. The mutual coupling in arrays of UWB biconical antennas and the radiation patterns are analyzed in time domain from measurement data in frequency domain. The contribution of MEA in UWB communications is evaluated in terms of Signal to Noise Ratio (SNR) gain from measured radio channel in Line Of Sight (LOS) and Non Line Of Sight (NLOS) environments.
