The past two decades have witnessed an unprecedented growth in the study and implementation of different short-range wireless services. However, the deployment of multiple short-range communication techniques has led to an overpopulation of the radio spectrum. Ultrawide-band (UWB) technology aims to offer an alternative to this spectrum scarcity as it can coexist with other radio technologies [Bluetooth, Worldwide Interoperability for Microwave Access (WiMAX), and Wireless Local Area Network (WLAN)] while causing minimal interference. The prospects of UWB technology allowing high data rate (up to 500 Mb/s) with low power consumption (<0.5 mW) up to a typical range of 10 m have escalated their demands over other short-range communication systems.

UWB 滤波器技术的两个十年：UWB 带通滤波器设计的进步和​​新出现的挑战


过去二十年见证了不同短程无线服务的研究和实施空前的增长。然而，多种短程通信技术的部署导致了无线电频谱的过度使用。超宽带 (UWB) 技术旨在为这种频谱稀缺提供替代方案，因为它可以与其他无线电技术[蓝牙、全球微波接入互操作性 (WiMAX) 和无线局域网 (WLAN)] 共存，同时将干扰降至最低。 UWB 技术的前景允许高数据速率（高达 500 Mb/s）和低功耗（<0.5 mW），典型范围可达 10 m，这使得他们对其他短距离通信系统的需求不断升级。
