Coplanar Wave Guide Fed Dual Band Antenna Loaded with Metamaterial Split Ring Resonator

摘要

Recently, antenna design based on metamaterial has become more common due to their improved bandwidth and radiation. In addition, for inherent impedance matching coplanar wave guide (CPW) antennas are used. In this papers, a high gain CPW fed dual bands antenna employed with metamaterial is demonstrated. Two circular rings are used as a radiating layers in the design, and the split rings resonator (SRR) element is loaded on the ground level to improve antenna output. Measured-results achieved resonance at 4.2 GHz (2.2-6.2 GHz) and 8.2 GHz (7-10.5 GHz) with a gain of above 2 dBi throughout the operational bands and with a high gain of 7 dBi at 10 GHz.
