Recently, antenna and its feed system in wireless communications require to be multifunctional for enhancing flexibility and feasibility, such as easy of integrate, low-profile, inexpensive and ease of fabrication, and wideband or multiband operating.The objective of the project is to design and develop a simple monopole antenna based on composite metamaterial resonators for multiband operation...

Superconducting split-ring resonator arrays allow to overcome two main limitations affecting metallic metamaterial resonating in the terahertz (THz) range: ohmic losses and tunability of their optical response. In this work, we design experimentally realize direct complementary square superconducting YBa2Cu3O7 (YBCO) resonators working THz spectral range. The purpose paper is show how resonance...
