Maximum Gain, Effective Area, and Directivity
Mats Gustafsson, Miloslav Capek
Fundamental bounds on antenna gain are found via convex optimization of the current density in a prescribed region. Various constraints are considered, including self-resonance and…
Modal Tracking Based on Group Theory
Michal Masek, Miloslav Capek, Lukas Jelinek +1
Issues in modal tracking in the presence of crossings and crossing avoidances between eigenvalue traces are solved via the theory of point groups. The von Neumann-Wigner theorem is…
Optimal Planar Electric Dipole Antenna
Miloslav Capek, Lukas Jelinek, Kurt Schab +4
Considerable time is often spent optimizing antennas to meet specific design metrics. Rarely, however, are the resulting antenna designs compared to rigorous physical bounds on tho…
Shape Synthesis Based on Topology Sensitivity
Miloslav Capek, Lukas Jelinek, Mats Gustafsson
A method evaluating the sensitivity of a given parameter to topological changes is proposed within the method of moments paradigm. The basis functions are used as degrees of freedo…
Trade-off Between Antenna Efficiency and Q-Factor
Mats Gustafsson, Miloslav Capek, Kurt Schab
The trade-off between radiation efficiency and antenna bandwidth, expressed in terms of Q-factor, for small antennas is formulated as a multi-objective optimization problem in curr…
