Efficient Radiation by Electrically Small Antennas made of Coupled Split-ring Resonators
In this paper, coupled split-ring resonators (SRRs) are used to construct the electrically small antennas. We show that through strong magnetic coupling, the coupled SRRs composite can oscillate at a wavelength much larger than its total size. Due to its magnetic dipole feature, the coupled SRRs composite allows the electromagnetic (EM) power to radiate and hence forms the electrically small an...

متن کاملElectrically Small Antenna Inspired by Spired Split Ring Resonator
A simple metamaterial resonator structure based efficiency electrically small semi-circular loop antenna (ESSCLA) is proposed. It is demonstrated numerically that capacitance offered by the simple metamaterial resonator structure can counteract the inductive impedance of the ESSCLA at the resonance frequency. The overall structures of ESSCLA can be fabricated on one dielectric substrate, and ma...
متن کاملMetamaterial-Based Efficient Electrically Small Antennas
A metamaterial paradigm for achieving an efficient, electrically small antenna is introduced. Spherical shells of homogenous, isotropic negative permittivity (ENG) material are designed to create electrically small resonant systems for several antennas: an infinitesimal electric dipole, a very short center-fed cylindrical electric dipole, and a very short coaxially-fed electric monopole over an...
متن کاملTuning the nonlinear response of coupled split-ring resonators
We introduce the concept of controlling the nonlinear response of the metamaterial by altering its internal structure. We experimentally demonstrate tuning of the nonlinear response of two coupled split-ring resonators by changing their mutual position. This effect is achieved through modification of the structure of the coupled resonant modes and their interaction with the incident field. By o...
