In this paper, the impact of the ground plane reduction imposed by modern wireless terminals on the antenna performance is evaluated. Numerical results in terms of antenna efficiency andQ-factor are discussed for two different antenna geometries.
This paper discusses the exploitation of spline-based geometries in the synthesis of Ultra-Wideband (UWB) antennas. The synthesis is carried out in the time-domain by using the antenna efficiency and the system fidelity as indexes of the antenna …
