Abstract :
The antenna impedance of a nanodipole can be matched to a metal-insulator-metal (MIM) waveguide impedance by the aid of a shunt stub connected at the feed point. Generation of a circularly polarized wave is numerically demonstrated by a rectangular spiral structure fed by the MIM waveguide.
