Planar Tapered Loop Antennas for Ultra-Wideband Radio Systems
Recently, ultra-wadeband (UWB) radio technology has found a variety of applications in science and engineering communities, such as imaging, location tracking, ground penetration radar, and low cost and short-range communications. One of the challenges of the implementation of UWB radio systems is the development of a suitable antenna that can be operated over an ultra wide bandwidth allocated by the Federal Communication Commission. When considering the design of UWB antennas, not only the usual specifications over the entire frequency range, such as input impedance, gain, polarization, and radiation pattern, etc., but also a good time-domain performance, i.e. the impulse response with minimal distortion, are required.
