Antenna Bandwidth Optimization with Single Frequency Simulation

Cismasu, Marius LU and Gustafsson, Mats LU (2014) In IEEE Transactions on Antennas and Propagation 62(3). p.1304-1311
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)

within 20% of their corresponding physical bound. (Less)
