Resumen
In this paper, the complementary split ring resonator (CSRR) is studied and applied to design a printed ultra wideband (UWB) antenna with dual band-notched characteristics. Dual band-notched function is obtained by incorporating the CSRR in the radiating element and the ground plane of the proposed UWB antenna. The designed antenna has a small size and operates over the frequency band from 3.2 GHz to 13.5 GHz, with dual-band rejection at 3.5 GHz (WiMAX band) and the other at 5-6 GHz (WLAN band). The antenna electromagnetic characteristics such as the S (11) parameter, the radiation pattern and the gain are simulated using HFSS and CST. The obtained results are in good agreement and show that the proposed antenna can be used for UWB applications.
