Journal ArticleDOI
Local Metamaterial-Based Waveguides in Gaps Between Parallel Metal Plates
TL;DR: The ridge gap waveguide as mentioned in this paper is a metamaterial-based waveguide that can be realized in a narrow gap between two parallel metal plates by using a texture or multilayer structure on one of the surfaces.
Journal ArticleDOI
Artificially soft and hard surfaces in electromagnetics
TL;DR: In this paper, the concept of soft and hard surfaces is treated in detail, considering different geometries, and it is shown that both the hard and soft boundaries have the advantage of a polarizationindependent reflection coefficient for geometrical optics ray fields, so that a circularly polarized wave is circularly polarization in the same sense after reflection.
Journal ArticleDOI
Correlation and capacity of MIMO systems and mutual coupling, radiation efficiency, and diversity gain of their antennas: simulations and measurements in a reverberation chamber
Per-Simon Kildal,Kent Rosengren +1 more
TL;DR: This work explains how MIMO and diversity antennas with mutual coupling can be analyzed by classical embedded element patterns that can be computed by standard computer codes and how the radiation efficiency, diversity gain, correlation, and channel capacity can be measured in a reverberation chamber.
Journal ArticleDOI
Design and experimental verification of ridge gap waveguide in bed of nails for parallel-plate mode suppression
Per-Simon Kildal,Ashraf Uz Zaman,Eva Rajo-Iglesias,Esperanza Alfonso,Alejandro Valero-Nogueira +4 more
TL;DR: In this paper, the ridge gap waveguide is used to verify the large bandwidth and low losses of the quasi-transverse electromagnetic (TEM) mode propagating along the guiding ridge.
Journal ArticleDOI
Radiation efficiency, correlation, diversity gain and capacity of a six-monopole antenna array for a MIMO system: theory, simulation and measurement in reverberation chamber
Kent Rosengren,Per-Simon Kildal +1 more
TL;DR: In this article, a six-monopole circular antenna array for use in a MIMO system is considered and the authors show how to calculate the embedded element patterns, both by classical analytical modeling and by the method of moments.
