Dissipation Factors of Spherical Current Modes on Multiple Spherical Layers
Vit Losenicky, Lukas Jelinek, Miloslav Capek +1
Radiation efficiencies of modal current densities distributed on a spherical shell are evaluated in terms of dissipation factor. The presented approach is rigorous, yet simple and…
Energy Stored by Radiating Systems
Kurt Schab, Lukas Jelinek, Miloslav Capek +4
Though commonly used to calculate Q-factor and fractional bandwidth, the energy stored by radiating systems (antennas) is a subtle and challenging concept that has perplexed resear…
Fundamental bounds on MIMO antennas
Casimir Ehrenborg, Mats Gustafsson
Antenna current optimization is often used to analyze the optimal performance of antennas. Antenna performance can be quantified in e.g., minimum Q-factor and efficiency. The perfo…
