“…Different techniques have been used for the miniaturization of metamaterial unit‐cells, such as using fractal and spiral resonators . Recently, metamaterial structures have been used for beam‐tilting, gain enhancement, and frequency and beam switching applications in microwave and millimeter‐wave antennas . In all of these cases, the main role of the metamaterial medium is to provide a refractive index that is different from the host medium when interacting with the incident electromagnetic wave.…”

A novel class of planar metamaterial unit-cells consisting of a peace logo pattern is presented. A significant advantage of the proposed peace-logo planar metamaterial (PLPM) unit-cell over existing designs is its tunability, simplicity, and compatibility with microstrip structures. The theoretical analysis is founded on the famous transmission-line theory for the metamaterial concept. Then, the tunable dual-band two-sided PLPM (TSPLPM) unit-cell is designed by printing a similar PLPM pattern at the bottom of the substrate. The influence of the bottom PLPM pattern on the resonance frequencies of the unit-cell was analyzed by performing numerical simulations using CST Microwave Studio 2017 and HFSSv15 simulators. The results of the numerical simulations demonstrated that the proposed TSPLPM has the ability to control the resonance frequencies over 50 GHz-75 GHz for millimeterwave applications.
