- Abstract
- A method to compute antenna Q using an electromagnetic
simulation at a single frequency is described. This
method can easily be integrated into global optimization algorithms.
In this way the optimization time of some antenna
parameters, e.g., bandwidth, may be significantly reduced. The
method is validated by direct comparison with the physical bound
of the analyzed structure. Numerical examples for rectangular
antennas and antennas with a rectangular ground plane illustrate
the integration of the method into a genetic algorithm. The results
predicted by optimization agree very well with those obtained
using a commercial electromagnetic solver. These... (More) - A method to compute antenna Q using an electromagnetic
