Nano-antenna apparatus and method

Abstract

A nano-antenna apparatus (or equivalently a nano-antenna device) comprises a first conducting surface, a second conducting surface, a gap region between a first conducting surface and a second conducting surface and at least one discharge switch at least one discharge switch cooperates with first conducting surface, a second conducting surface to form a substantially continuous closed surface enclosing a volume. This volume may be substantially similar to a spheroid, a prolate spheroid, an oblate spheroid, a Cartesian rectangular solid or other shape. This volume may enclose at least one electric device. A dimension of the volume and a dielectric constant characterizing a dielectric layer may be chosen so as to yield a desired frequency response. Further, this volume may partition outside energy from inside energy, causing the former energy to radiate away. This invention further teaches a method for transmitting UWB impulse. This method comprises the steps of charging a first conducting surface with respect to a second conducting surface, and discharging a first conducting surface with respect to a second conducting surface such that the discharging forms a substantially continuous closed conducting shell from a first conducting surface and a second conducting surface. In alternate embodiments the discharging or charging may be adiabatic. Discharging may be positioned in time in accordance with a pulse position modulation scheme. Charging may be polarized in accordance to a flip or BPSK modulation scheme. Discharging may be effected by diodes, transistors, or MEMS devices.
