Figure 32 shows a photo of the fabricated rectenna. The simulated and measured reflection coefficient is shown in Figure 33. The measured results show that the filtenna has 10 dB impedance of the first band from 2.16 to 2.53GHz, the second band is from 4.58 to 5.8GHz, and the third band is from 26.8 GHz to 30 GHz. The simulated and measured gains are shown in Figure 34. The first and second bands have peak measured gain level of 1.95 and 3.76 dBi, respectively. The third band

## 5.4 Simulation and measurement results of filtenna

The equivalent circuit model simulation results of the filtenna system shown in Figure 27 is determined by merging the three parts component's equivalent circuit,
