Abstract

This work investigates the influence of geometric variations in dipole micro/nano antennas, regarding their implications on the characteristics of the electric field inside the gap space of antenna monopoles. The gap is the interface for a metal-Insulator-Metal (MIM) rectifier diode and it needs to be carefully optimized, in order to allow better electric current generation by tunneling current mechanisms. The arrangement (antenna + diode or rectenna) was designed to operate around 30 Terahertz (THz).
