Abstract
In various embodiments, a booster antenna for a chip arrangement, for example a smart card, is provided. The booster antenna can have: a first electrical circuit, which forms a first resonant circuit with a phase resonance; and a second electrical circuit, which forms a second resonant circuit with a phase resonance and/or absolute resonance; wherein the first electrical circuit and the second electrical circuit are coupled to one another.
