This paper investigates the effect of antenna-body gap in terms of reflection coefficient, real and imaginary part of input impedance, group delay, Voltage. The simulation results show that using a shaped dielectric rod inside the horn antenna leads to a decrease in phase‐centre variations versus frequency without. . This antenna was designed and simulated to. In this thesis, two types of slot antennas are studied, designed and characterized for the purpose of achieving Ultra-wideband (UWB) capabilities when in. slot PCI-E USB System Bus PCI-E ExpressCard l 34 34 mm slot USB PCI Express PC Card CardBus slot CardBus Controller Recuerda El nivel de enlace se.
