Metamaterial loaded CB-CPW Antenna for ISM band and 5G Applications

Abstract

Metamaterials/Spilt Ring Resonator (SRR) loaded with conductor backed coplanar waveguide fed (CB-CPW) patch antennas are widely applicable in medical field for monitoring on-body signals. The main characteristic of this type of antenna have high gain and bandwidth. The main advantages of CPW fed have lower attenuation and dispersion. The prototype resonated frequencies are 2.44GHz and 3.5GHz. The 2.36GHz to 2.48GHz are used for ISM band applications. The 3.3GHz to 3.6GHz are used for WiMAX/5G medical service applications. The designed antenna reflection coefficients are −27dB at 2.43GHz, −13dB at 3.5GHz for non-SRR loaded structure, −19dB at 2.44GHz and −26dB at 3.5GHz.
