Abstract :
Performance of wireless sensor systems are evaluated on the basis of the quality of data communication and efficiency of power transmission. This work presents the design methodology of a miniaturized tag antenna for remote powering of wireless sensor systems at 2.45 GHz ISM band. Accurate simulations of the rectifier input impedance aimed at the maximization of transmitted power are presented. Simulation results combined with simple transmitting antenna scattering parameters and cable loss measurements provide straightforward characterization of the fabricated tag antenna. The experimental measurements on a 12×10mm miniaturized antenna designed with the proposed approach show a gain of -5.9 dB close by 0.8 dB to the simulation results.
