Abstract: The hexagonal shaped patch antenna loaded with hexagonal complementary split ring resonator is presented for multiband characteristics. The better impedance matching is achieved by employing the HCSRR, the metamaterial element in the main radiating patch. The proposed antenna resonate at 2.1 GHz, 6.5 GHz,10 GHz frequency bands due to the loading of metamaterial element Hexagonal Complementary Split Ring Resonator (HCSRR). The entire size of the antenna is 20 × 21 × 0.8 mm3. The dielectric material used for fabricating the antenna is FR-4 having the dielectric constant of 4.4 (εr) respectively. The proposed antenna offers better impedance matching, multiband and good radiation pattern characteristics. Parametric study is done for various width of HCSRR slots and by split gap for scrutinizing several characteristics of the proposed antenna. The HCSRR offers negative permittivity characteristics by its pass band behavior. The designed antenna is desirable for L, S and C band applications.
