| Descripción: | This paper summarizes our recent advances in antenna designs for ultra wideband (UWB) applications. Two types of monopoles are studied and developed in our research group. The first type belongs to the electric monopole with a circular disc fed by three different feeding structures. The second type is the magnetic monopole with an elliptical slot. The performances of these two types of antennas are evaluated in both frequency and time domains. The important design parameters for achieving optimal operations are also analyzed. It is shown that both electric and magnetic monopoles can provide ultra wide bandwidth with nearly omni-directional radiation patterns over the entire frequency band. In addition, the impulse responses of the selected antennas are shown to correspond well to the frequency domain characteristics. |
