A few years after the early investigation on ultra-wideband (UWB) wireless system, considerable research efforts have been put into the design of UWB antennas and systems for communications. These UWB antennas are essential for providing wireless wideband communications over very short distances at very low power densities. This chapter presents numerical analysis of a small slotted UWB antenna by studying its current behavior. The active and neutral zones of antenna are determined before applying slots on its patch radiator. This is due to any modification applied on this active zone means disturbing its current distribution and affect to its impedance characteristics. It is shown from simulated and measured results that L and U slotted on the patch antenna result an UWB bandwidth. This simulation was performed by using the Zeland simulation software.
