Abstract :
In this paper, a band notched ultra-wideband antenna integrated with complementary split ring resonator (CSRR) is proposed and investigated. The proposed antenna not only covers the UWB frequency spectrum but also avoids interference with HIPERLAN/2 (5.15 GHz - 5.35 GHz) by giving a notch band from 4.98 GHz to 5.37 GHz. The centre frequency of the notched band is 5.2 GHz at which the wireless LAN (HIPERLAN/2) in Europe is assigned. The notch band in the proposed paper is achieved by etching CSRR in the radiating patch. The complementary split ring resonator acts as a bandstop filter and hence enables the rejection of any undesired band within the passband of the antenna. The proposed antenna operates from 2.7 GHz to 13.7 GHz for voltage standing wave ratio (VSWR) less than 2, except the notch band of 4.98 GHz to 5.37 GHz.
