Journal ArticleDOI
Corporate-Fed Planar 60-GHz Slot Array Made of Three Unconnected Metal Layers Using AMC Pin Surface for the Gap Waveguide
Abbas Vosoogh,Per-Simon Kildal +1 more
TL;DR: In this paper, a high efficiency corporate-fed 8×8-slot array antenna in the 60 GHz band is presented, which is built using three unconnected metal layers based on Artificial Magnetic Conductor (AMC) in gap waveguide technology.
Journal ArticleDOI
Soft and hard horn antennas
Erik Lier,Per-Simon Kildal +1 more
TL;DR: Horn antennas with soft and hard boundaries are analyzed and the dependency between the edge taper directivity, and sidelobes is calculated based on the solution to the spherical hybrid modes in a conical horn with arbitrary wall impedances.
Journal ArticleDOI
Detection of a polarization imbalance in reverberation chambers and how to remove it by polarization stirring when measuring antenna efficiencies
TL;DR: In this article, it was shown that the results depend strongly on the orientation of the antenna under test and thereby on its polarization, and how this imbalance can be removed by using three orthogonal fixed antennas instead of one.
Journal ArticleDOI
Study of Q-factors of ridge and groove gap waveguide resonators
TL;DR: In this paper, a study of Q-factors of resonators made in ridge and groove gap waveguides is presented, where the resonators are made of copper and the AMC used is a textured surface of metallic pins.
Journal ArticleDOI
Planar Dual-Mode Horn Array With Corporate-Feed Network in Inverted Microstrip Gap Waveguide
TL;DR: In this article, a 4 × 4 planar dual-mode horn array with low loss corporate feed network realized by using an inverted microstrip gap waveguide is presented, where the diameters of the horn apertures are larger than two wavelengths to allow more space for the feed network and thereby lower conductive losses.
