SRR loaded crescent patch-koch curve fractal for dual band applications

A squashed symmetric coplanar strip (ACS) fed - monopole antenna is offered, comprising a SRR loaded modified half moon patch with koch curve fractal shape is used for dual band applications. The antenna is crafted on the FR4 dielectric substrate of 20 mm × 18 mm × 1.6 mm with relative permittivity 4.4. To aggravate dual band characteristics, fractal geometries is stamped on the front side of crescent patch resonator and Split ring Metamaterial resonator is positioned back side of the FR4 substrate, bonus resonances are agitated. The antenna projected operates at dual bands, covering 4.62 GHz at C band and 11.14 GHz at X band. The result shows high-flying performance, high advantageous return loss, and fine radiation pattern with diffident gain across the dual bands.
