Antenna Bandwidth Optimization with Single Frequency Simulation

Cismasu, Marius LU and Gustafsson, Mats LU orcid (2013) In Technical Report LUTEDX/(TEAT-7227)/1-19/(2013)
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 results suggest that the method can be used to yield antennas with Q factors within 20%... (More)
