Journal ArticleDOI
Steering the Beam of Medium-to-High Gain Antennas Using Near-Field Phase Transformation
TL;DR: In this paper, the beam of a resonant cavity antenna is steered by transforming phase of the antenna near field using a pair of totally passive metasurfaces, which are located just above and parallel to the antenna.
Journal ArticleDOI
Multiobjective Particle Swarm Optimization to Design a Time-Delay Equalizer Metasurface for an Electromagnetic Band-Gap Resonator Antenna
TL;DR: In this paper, an efficient particle swarm optimization (PSO) algorithm was developed to design a near-field time-delay equalizer metasurface (TDEM) for the purpose of improving directivity and radiation patterns of classical electromagnetic band-gap resonator antennas.
Journal ArticleDOI
Dielectric Phase-Correcting Structures for Electromagnetic Band Gap Resonator Antennas
TL;DR: In this article, a phase-correcting structure (PCS) for an electromagnetic band gap (EBG) resonator antenna (ERA) was proposed to transform a non-uniform phase distribution to a nearly uniform phase distribution.
Journal ArticleDOI
Single-Dielectric Wideband Partially Reflecting Surface With Variable Reflection Components for Realization of a Compact High-Gain Resonant Cavity Antenna
TL;DR: In this paper, the authors presented a design methodology for a compact low-cost partially reflecting surface (PRS) for a wideband high-gain resonant cavity antenna (RCA) which requires only a single commercial dielectric slab.
Journal ArticleDOI
A Low-Profile Printed Planar Phase Correcting Surface to Improve Directive Radiation Characteristics of Electromagnetic Band Gap Resonator Antennas
TL;DR: In this article, a low-profile printed planar phase correcting surface (PCS) was designed and fabricated to demonstrate performance enhancement of conventional electromagnetic band gap resonator antennas (ERAs) by improving their aperture phase distributions.
