A Novel Design of Multiband Monopole Antenna Loaded with Complementary Split Ring Resonator

A novel patch antenna having Complementary Split Ring Resonator (CSRR) with meandered Coplanar Waveguide (CPW) fed is proposed in this paper. A compact 3 band structure is developed by engraving slots and meandered CPW fed on the radiating element. A triple-band antenna with its reduced size is achieved by etching circles outside the patch along with CSRR slots and with Modified Ground Plane (MGP). The proposed antenna displays acceptable results at all values of resonance, in terms of enhanced bandwidth, return losses, VSWR. The simulated results for different designs are discussed and compared among them. Parametric study is also implemented for different ring widths and etching of circles with different radius on the proposed design. In order to validate the results CSRR permittivity and permeability characteristics are explained. The proposed antenna with greater qualities is suitable for C-band, S-band, Wireless Local Area Network (WLAN), WIMAX applications.
