Abstract

Narrowband antennas are not suitable for UWB systems. This paper emphasizes on the design for mono-cone and sphere-loaded mono-cone antennas. The voltage standing wave ratio (VWSR), input impedance, fidelity coefficient of radiated pulse, radiant efficiency and radiant patterns are computer calculated. Simulated results confirm that the mono-cone and sphere-loaded mono-cone antennas be of good ultra-wide band performance. Sphere-loaded mono-cone antennas are better to radiate ultra-wide band pulses than mono-cone antennas on condition of the same size of antennas.
