Summary:
This paper investigates the time-domain characteristics of an ultrawideband (UWB) dielectric resonator antenna (DRA) for two UWB input pulses. The computed spectrum amplitude of a fifth-order Gaussian pulse has better compliance, as per FCC mask, compared to a first-order Rayleigh pulse. The correlation between the input pulses and the radiated pulses in many directions were found to be less when the antenna is excited by the first-order Rayleigh pulse. On the contrary, with the fifth-order Gaussian pulse excellent correlation factors are achieved in most directions. Therefore, this DRA with the fifth-order are suitable for an impulse radio (IR) UWB system.
