In a number of applications, it is necessary a network which could provide well-defined impedance values at different frequencies, that is a multiband impedance matching network. In this paper, we present a novel approach for dual-band impedance matching network design using multiresonant circuits. These multiresonant circuits provide short and open circuit conditions at different frequencies, thus enabling and disabling capacitors and inductors to form the desired impedance matching network. To illustrate the proposed method, experimental and simulation results of a dual-band impedance matching network operating at frequencies 2.4 GHz and 5.2 GHz are also presented.
