This is a hot topic due to immediate demand from industry. However, the key design issues are often ignored, in particular by the students. In this course, these issues will be highlighted from an application point of view. The theoretical analysis is also given to help students understand the broadband radiation behavior well. The following is the abstract of the course.
The research and development of ultra-wideband (UWB) technology has greatly spurred the design of small broadband antennas. The requirements for the UWB antennas include consistent impedance and radiation performance over an ultra-wide bandwidth of 3.1-4.8GHz/6-10.6GHz/3.1-10.6GHz. The miniaturization of the antennas becomes the most critical design challenges in commercial UWB systems such as high-speed wireless USB dongles. This course reviews the development of the small UWB antennas. The key design issues of the UWB antennas such as planar printed UWB antennas are highlighted. The new techniques to reduce the effect of ground plane on the antenna performance, further miniaturize antenna, co-design antenna with RF filters are elaborated. The latest applications of small printed antennas in wireless UWB systems are described in brief.
