The Radiation Efficiency Cost of Resonance Tuning
L. Jelinek, K. Schab, M. Capek
Existing optimization methods are used to calculate the upper-bounds on radiation efficiency with and without the constraint on self-resonance. These bounds are used for the design…
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…
