Electrically 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...

Broadband compact microstrip patch antenna design loaded by multiple split ring resonator superstrate and substrate

We present microstrip patch antenna loaded with multiple split ring resonator substrate and superstrate. We analyze how the loading of split ring resonator superstrate and substrate can improve the bandwidth compared to the simple microstrip patch antenna and microstrip patch antenna loaded with split ring resonator superstrate. Another important observation is made for multiple split ring reso...

Improved Split - Ring Resonator for Microfluidic Sensing

We present a method of making low loss split-ring resonators for microfluidic sensing at microwave frequencies using silver coated copper wire. We show that a simple geometric modification and the use of square cross-section wire give greater electric field confinement in the capacitive region of the resonant sensor. We use a combination of theoretical analysis, finite element simulations and e...

A Frequency Band Enhancement of Miniaturized Rectangular Waveguide Antenna Using Infinity Shaped Split Ring Resonator

this paper presents a miniaturized open-ended rectangular waveguide antenna radiating below the cut-off frequency of the waveguide with a large bandwidth. Waveguide miniaturization is achieved by periodically loading the antenna with electromagnetic metamaterials consisting of infinity shaped resonators. The metamaterial cell is designed to have a high effective dielectric permittivity in the f...
