Dielectric Resonator Metasurface for Dispersion Engineering
We introduce a practical dielectric metasurface design for microwave frequencies. The metasurface is made of an array of dielectric resonators held together by dielectric connections thus avoidingExpand
Design of microstrip-fed proximity-coupled conducting-polymer patch antenna
A conducting-polymer patch antenna was fabricated by a screen-printing technique. Polyaniline (Pani) films of conductivity 6000 S/m, permittivity 6000 and thickness 100 µm have been used as aExpand

Study of an Electrochemically-Deposited 3-D Random Fractal Tree-Monopole Antenna
A 3-D fractal-tree monopole antenna was realized using electrochemical deposition technique. Experimental results on the return loss over the band 1-20 GHz and radiation patterns at all resonatingExpand
Design of a new type of metamaterial radome for low frequencies
A new type of radome was designed around 2 GHz, comprising alternately layers with negative permeability and positive index of refraction materials.The negative permeability, obtained by the squareExpand
Design of a frequency reconfigurable patch antenna using capacitive loading and varactor diode
A frequency reconfigurable antenna optimized to operate at 2.45 GHz was presented. The antenna consists on a square patch excited by a coaxial probe. The frequency agility was achieved by integratingExpand
A COMPACT SPLIT RING RESONATOR ANTENNA FOR WIRELESS COMMUNICATION SYSTEMS
In this paper, we report a new design of a compact antenna based on the use of split ring resonator (SRR). The designed antenna consists of two SRRs, with the same geometrical parameters, printedExpand

Superdirective and low profile metamaterial-inspired antenna
In this paper, a superdirective and low profile metamaterial-inspired antenna is reported. The proposed structure consists of the association of Split-Ring Resonator (SRR) and a monopole. ThisExpand
Capacitively Loaded Loop-Based Antennas with Reconfigurable Radiation Patterns
A class of metamaterial-inspired antennas having reconfigurable radiation patterns is proposed. They consist of a driven monopole antenna with one- and two-capacitively loaded loop (CLL), near fieldExpand
