Planar Monopole UWB Antennas with Cuts at the Edges and Parasitic Loops

In this paper, we analyze an antenna for application in ultra wideband systems. This antenna is composed by one planar monopole with cuts at the edges and two parasitic loops. The numerical analysis of the antenna was done by the Method of Moments (MoM). For comparison, some of the calculations were also made by the commercial software IE3D. The results of this analysis show that the antenna has excellent impedance matching in all frequency range of UWB systems.
