At present, most of the mainstream wireless access point for the dual band 2.4G and 5G set, so the design of the rectenna frequency is also for this dual band.

Only a single feed point to achieve the dual band, 2.4G band is the form of microstrip antenna for resonance, 5G band is the form of slotted antenna for resonance, because only a single feed is used, the input impedance of both resonators is designed at 50Ω. Using the simulation software through the appropriate adjustment of the antenna size can be a good return loss of -33dB and -25 dB, a radiation pattern gain of 7.7 dBi and 8.8 dBi, more than 90% and 80% of the radiation efficiency.
