Design and Measurements of Ultra-Wideband Antenna
International Journal of Communications, Network and System Sciences, 2010 This paper describes the design, realization and experimental measurements of an antenna element to operate at ultra-wideband (UWB) spectrum. The type of this antenna is a circular disk monopole (CDM), with two notches opposite to each other at two sides of the disk. The feed of the antenna is a coplanar waveguide (CPW).
