Title : Step by step improving characteristics of UWB antenna utilizing meta-material and slot
Mustafa Jawad, Jamal.M.RAsool,

Abstract : It is planned to develop a more compact ultra-wideband (UWB) patch antenna employing meta-materials. The total size is reduced, and the simulated impedance bandwidth operates from 3.4 to 9.1 GHz for a single-slot antenna, with the bandwidth improved (3.04 to 14.35 GHz) with an S-parameter of less than -10 dB by etching another slot in the patch and using CSRR instead of wire in the back of the ground plane. These two antennas have a bandwidth of 5.7GHz and 11.33GHz, respectively. Both substantial horizontal radiation and practical properties have been observed. As a result, these antennas could have some specific applications in the future for UWB wireless communications.
