Abstract
A co-planar waveguide fed ultra-wideband antenna with dual notches at 4 and 5.4 GHz is proposed. Two modified complementary split ring resonator (CSRR) shaped etched slots on the radiating patch generate the required dual notches. The notch positions are functions of CSRR profile dimensions. In order to improve the pass band characteristics of the proposed structure, defected ground structures (DGS) are introduced, one close to the feed line (lower DGS) and other at the upper corner edge. The structure is small in size measuring 26.75 × 33.5 × 1.6 s mm3.
