Summary:The pulse preserving capability in terms of system fidelity factor (SFF) of a new ultrawideband dielectric resonator antenna (DRA) made of a dispersive material is evaluated in this paper. The proposed antenna is developed based on a special frequency-dependent dispersive material whose relative permittivity is inversely proportional to the frequency square. Due to the small variation of gain and stable radiation pattern of the proposed antenna, the calculated SFF is very close to unity, showing the high quality of pulse transmission through the proposed antenna system. Overall, the proposed antenna shows ultrawide bandwidth, stable radiation pattern and gain, and excellent pulse-preserving capability, which is promising for future wideband high-speed wireless communication systems.
