In a number of applications, a matching network capable of providing specified impedances at different frequencies is necessary. In this brief, we present a novel technique for switchless multiband impedance matching networks based on multiresonant circuits. To illustrate this, simulation results of dual-band and triband networks are also presented. In addition, a dual-band impedance matching network has been implemented and evaluated. The dual-band impedance matching network presents two specified impedances, one at 433 MHz and the other at 915 MHz with 0.82 and 0.20 dB of insertion losses, respectively.
