Recent advances in the techniques of nanoantennas design and prototypes have led to create more efficient and reliable electronic devices. Otherwise, a commercial device has not been achieved yet. In this work we describe two possibilities of organic nanoantennas made of dendrimer and graphene. Our finds from the simulations are consistent with: (i) a rod antenna with similar characteristic as usual resistor coupled with field effect transistor device; (ii) high parasitic capacitance (from 0.36 mu F and 0.43 mu F) and operational frequency (tenths of THz); (iii) operational voltage around rectification (0.67 V and 0.82 V).
