Metamaterial Structures Composed of Multi-Layer Ceramic Capacitors for Antenna Applications

The metamaterial design process provides significant change to the material selection of the general antenna design process. To apply metamaterials to small antennas, multi-layer ceramic capacitors (MLCCs) has been investigated to compose a small size and a compact structure for each unit cell. In this paper, the open and closed metamaterial structures composed of MLCCs are designed by the eigenmode and driven modal simulations. These unit cells are employed to a slender and small magnetic current source and a low-profile and omnidirectional antenna. The proposed two types of the antennas can overcome a limitation of the conventional antenna size.
