This paper presents an E-ring shaped printed monopole antenna for UWB applications with dual notched bands performance. In order to generate single frequency band notch function, we applied a U-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an E-ring shaped radiating patch created and a dual band-notch function can be achieved. The measured bandwidth of the proposed antenna is from ۲.۷۵ GHz to ۱۱.۴۳ GHz (۱۱۰%) for VSWR < ۲. The proposed antenna offers two notched bands, covering all the ۵.۲/۵.۸GHz of WLAN, ۳.۵/۵.۵ GHz of WiMAX and ۴-GHz of C bands ranges. Good radiation behavior within the UWB frequency range has been obtained. The antenna has a small dimension of ۱۰ *۱۷ mm۲.
