Dual Band Circular Patch Antenna based on Metamaterials
Keywords:Dual band, Split Ring Resonator, mushroom unit cell, Circular Polarization
A novel dual-band circular patch antenna with a circular mushroom unit cell is proposed. A circular slot is etched along the
diagonal of the circular patch antenna, which is loaded with the circular mushroom unit cell to achieve dual-band operation. Three other mushroom unit cells are designed simulated and studied. The negative order modes with Linear Polarization (LP) are observed from each mushroom unit cell, so these modes are combined to get Circular Polarization (CP) at a single frequency. To validate the results obtained from the simulation, one of the four antennas which are having good radiation characteristics is fabricated. The close relationship between simulation and measured results establish the usefulness of the antenna.
