Abstract
This paper presents an optimization problem formulation to design broadband antennas with optimal impedance matching considering that the source impedance is tunable inside a range. Usually an antenna is designed to match a given source impedance, which can be too constraining. The new optimization problem formulation is introduced to answer a less strict query: which impedance is optimal for the behavior inside a frequency range of a given antenna? The formulation is used to investigate Archimedean spiral antennas.
