Description
Summary:In order to prevent interference problem due to existing nearby communication systems within the ultra-wideband (UWB) operating frequency, a compact CPW fed triple-band-notched antenna using modified co-directional complementary split ring resonators (CSRRs) is proposed and investigated. The proposed antenna is realized by etching three modified co-directional CSRRs with different centers in the radiating patch. The measurement result shows that the proposed antenna can guarantee a wide bandwidth from 2 GHz to 16 GHz (VSWR? 2) with triple unwanted band-notches successfully. The proposed antenna occupies a compact area of 25 × 27.9 mm2 only. The antenna demonstrates omni-directional radiation patterns across almost the whole operating bandwidth, which is useful for UWB (3.1 GHz - 10.6 GHz) applications.
