Calculation of ring-shaped phase centers of feeds for ring-focus paraboloids
Jian Yang,Per-Simon Kildal +1 more
TL;DR: In this article, the phase center location of the ring-shaped phase center was calculated for a ring-focus paraboloid with the ring focus coinciding with the phase centre.
Journal ArticleDOI
MIMO Characterization on System Level of 5G Microbase Stations Subject to Randomness in LOS
TL;DR: The term random-LOS is introduced to describe the characterization of an example antenna in both RIMP and random- Los, to introduce a systematic approach to include the statistical properties of the user and his or her terminal, when characterizing the performance.
Proceedings ArticleDOI
Fundamental properties of canonical soft and hard surfaces, perfect magnetic conductors and the newly introduced DB surface and their relation to different practical applications including cloaking
TL;DR: In this article, the authors proposed an ideal canonical representation of an EBG surface for cloaking, which is based on an isotropic soft surface with boundary condition D n =B n = 0.
Journal ArticleDOI
Design of $F$ -Band Transition From Microstrip to Ridge Gap Waveguide Including Monte Carlo Assembly Tolerance Analysis
Astrid Algaba Brazalez,Jonas Flygare,Jian Yang,Vessen Vassilev,Mariano Baquero-Escudero,Per-Simon Kildal +5 more
TL;DR: In this paper, the authors describe the design and realization of a transition from a microstrip line to a ridge gap waveguide operating between 95 and 115 GHz, including simulations, measurements, and a Monte Carlo analysis of the assembly tolerances.
Proceedings ArticleDOI
Tripling bandwidth of hat feed by genetic algorithm optimization
TL;DR: Genetic algorithm optimization combined with V2D-FDTD simulations has been used to redesign the geometry of the Hat Feed and the new evolved feed has improved return loss properties while keeping the good overall efficiency of the original feed.
