Design and Analysis of Dual Notch Band Ultra-Wide Band Antenna Using Complementary Split Ring Resonator for Wireless Applications

摘要

Design of a novel compact microstrip patch antenna for Ultra-Wide Band with dual notch band characteristics is proposed in this paper. The Split Ring Resonator and Complementary Split Ring Resonator of different sizes are etched on the circular radiating patch, and by adjusting the dimensions of the resonator, the proposed antenna performance is improved. A full-wave electromagnetic tool has been used to analyze the effects of different parameters (radius of the patch, width of the feed, the overall size of the antenna and radius of CSRR) on the antenna performance. To validate the design, the proposed antenna is fabricated on a low-cost laminate of FR4 substrate with a dielectric constant of 4.4 and 1.6 mm thickness. The measured return loss, VSWR and radiation pattern are in good agreement with the fabricated UWB antenna.
