Eccentrically-Layered Active Coated Nano-Particles for Directive Near- and Far-Field Radiation
Photonics, 2015 The present work shows how the eccentricity in active nano-particles may lead to very interesting and rather directive near- and far-field radiation patterns.

Active coated nano rod antennas for enhanced and directive scattering phenomena
EPJ Applied Metamaterials, 2019 The scattering properties of a range of symmetric and asymmetric active coated nano rod antennas are investigated numerically. The active nano rods are composed of a silica dioxide nano-core coated with a silver nano-shell, and with a canonical gain ...

Broadband Electrically Small Circularly Polarized Directive Antenna [PDF]
IEEE Access, 2017 A broadband electrically small antenna with directive circularly polarized radiation is presented. It is composed of a compact single-feed crossed dipole driver, which is backed by a near-field resonant parasitic (NFRP) reflector to achieve the directive

UWB Directive Triangular Patch Antenna
International Journal of Antennas and Propagation, 2008 Compact directive UWB antennas are presented in this paper. We propose an optimization of the F-probe fed triangular patch antenna. The new design achieves an impedance bandwidth of 69% (3–6.15 GHz) and presents good radiation characteristics over the ...
