A dual-frequency antenna based on the
Sierpinski fractal with two parasitic patches to enhance the
impedance bandwidth is presented. An electrical circuit
model formed by RLC resonators is proposed to learn
about the antenna physical behavior and to achieve the
dual band operation minimizing a trial-and-error
numerical/ measurement proofs. The antenna has been
designed using a MoM commercial code and has been
experimentally tested, obtaining two bands with a
bandwidth around 7%(SWR<2) and similar radiation
pattern and gain.Peer ReviewedPostprint (published version
