Printed Wide Slot Ultra-Wideband Antenna

With the beginning of the new information era, necessity of wideband wireless communica‐ tions technology is increasing rapidly due to the need to support more users and to provide information with higher data transmitting rates. Ultra-wideband (UWB) technology could be the most suitable technologies that promise to revolutionize high data rate transmission and enable the personal area networking industry leading to new innovations and greater quality of services to the end users. A UWB system is found to be extremely useful and con‐ sists of various satisfying features such as high data rate, high precision ranging, fading ro‐ bustness, and low cost transceiver implementation. UWB is regarded as a very promising and fast emerging low-cost technology with uniquely attractive features inviting major ad‐ vances in wireless communications, sensor networking, radar, imaging, and positioning sys‐ tems [1, 2].
