CPW-Fed Quasi-Magnetic Printed Antenna for Ultra-Wideband Applications

An optimized coplanar-waveguide-fed quasi-magnetic printed antenna for ultra-wideband applications is described. A parameter study, motivated by a design procedure, allowed a substantial increase in the return-loss operational bandwidth. The numerically predicted performance was validated by means of physical measurements of fabricated samples. The measured radiation patterns of the antenna demonstrated its adequate radiation characteristics. The feed radiation was also investigated by means of physical measurements.
