A Fully Integrated Filtering Vivaldi Antenna With High Selectivity and Wide Out-of-Band Suppression
Autor: Ahmad Emadeddin, B. L. G. Jonsson
Publikováno v: IEEE Access, Vol 12, Pp 2690-2700 (2024)
This paper introduces a novel filtering approach that employs integrated periodic structures with a conventional Vivaldi antenna to achieve a fully integrated bandpass filtering antenna. The approach results in a wide out-of-band suppression, high pa

Quasi-Herglotz functions and convex optimization
Autor: Y. Ivanenko, M. Nedic, M. Gustafsson, B. L. G. Jonsson, A. Luger, S. Nordebo
Publikováno v: Royal Society Open Science, Vol 7, Iss 1 (2020)
We introduce the set of quasi-Herglotz functions and demonstrate that it has properties useful in the modelling of non-passive systems. The linear space of quasi-Herglotz functions constitutes a natural extension of the convex cone of Herglotz functi

Partially Transparent Jaumann-Like Absorber Applied to a Curved Structure
Autor: Alireza Motevasselian, B. L. G. Jonsson
Publikováno v: International Journal of Antennas and Propagation, Vol 2011 (2011)
A Jaumann absorber with its metal backing replaced with a combined low-pass and polarizer FSS is investigated with respect to its absorption and its polarization-dependent low-frequency transparency properties. This structure is applied to an idealiz

A 28-Port MIMO Cube for Micro Base Station Applications
Autor: C. I. Kolitsidas, B. L. G. Jonsson, Oskar Zetterstrom, Andres Alayon Glazunov
Publikováno v: IEEE transactions on antennas and propagation, 68(5):8951444, 3443-3452. IEEE
A novel multiband, dual-polarized, 28-port multiple-input multiple-output (MIMO) cube is presented. The cube structure enables dense placement of the antennas, whilst still allowing for low correlation between the individual antenna ports. The total

On bandwidth bounds for periodic antenna elements with a ground plane
Autor: Jari-Matti Hannula, B. L. G. Jonsson, Andrei Ludvig-Osipov
Publikováno v: 2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS).
In this paper, we compare two different bandwidth bounds on array antennas with a ground plane. The first of these bounds is based on the fact that the antenna can be seen as a passive system, which implies that its response can be described in terms

A New Unit-Cell Architecture Applied to Active Wide-Angle Scanning Phased Array
Autor: Ahmad Emadeddin, B. L. G. Jonsson
Publikováno v: 2021 15th European Conference on Antennas and Propagation (EuCAP).
In this paper, we propose a unit-cell element suitable designed for wide-angle scanning active phased array antennas. The design method utilizes the sub-array factor theory inside the unit-cell. The generalization shows that the unit-cell architectur
