This paper investigates the effect of antenna-body gap in terms of reflection coefficient, real and imaginary part of input impedance, group delay, Voltage. In this thesis, two types of slot antennas are studied, designed and characterized for the purpose of achieving Ultra-wideband (UWB) capabilities when in.
