Abstract :
A known Ultra Wideband (UWB) planar monopole antenna was modified and analyzed by implementing the FDTD methodology and by experiments. The modification is based on the current characteristics related to the skin effect. Then, it is verified that by introducing some modifications, it is possible to operate in different bands. Such bands are around 2.4 GHz, in the 5 - 6 GHz range, and at the UWB range (3.1-10.6 GHz).
