UWB 已经出现了大约二十年。广泛的测试和测量结果，以及从商业产品的设计和操作中获得的经验，都一致认为，由于 UWB 的固有特性，在许多环境和应用中，UWB 是一种非常有前途的技术。现在，无线通信正在占领更高的频率，而 UWB 范式甚至是传输技术的有效候选者。由于 UWB 的许多吸引人的特性与其传播特性有关，因此本文概述了 UWB 信号在不同频率信道上的行为，从极低频率（低于 1 GHz）到 3.1-10.6 GHz 频段，直至 60 GHz。最后，提出了在这个巨大频率跨度上的信道脉冲响应的通用表达式，解释了通过不同频率和不同环境下的各种信道测量活动观察到的所有现象和行为。
UWB has been on the scene for about two decades. Results of extensive tests and measurements, and experience acquired from the design and operation of commercial products, all concurred to depict UWB as a very promising technology in many context and applications, thanks to its intrinsic characteristics. Now, wireless communications are colonizing higher frequencies and the UWB paradigm is a valid candidate for a transmission technology even there. Since many attractive features of UWB are related to its propagation characteristics, this paper provides a synopsis of the behavior of UWB signals on channels at different frequencies, from very low frequencies, below 1 GHz, through the 3.1–10.6 GHz band, and up to the 60 GHz. Finally, a generalized expression is proposed for the channel impulse response over this huge frequency span, accounting for all phenomena and behaviors observed through a variety of channel measurement campaigns at different frequencies and in different environments.
