Abstract
A system, comprising a device including a circuit configured to produce a phase shift in a reflected signal, wherein a plurality of switchable phase bits are situated in parallel relative to one another within the device, wherein each switchable phase bit operates on a fraction of incident signal power, and wherein reflections from all parallel bits are recombined into a single signal reflected from the phase shifting device; and an antenna, wherein the antenna is a single antenna or an array of antennas.
Claims13
A system, comprising:
- (a) a device including a circuit configured to produce a phase shift in a reflected signal,
- (i) wherein a plurality of switchable phase bits are situated in parallel relative to one another within the device,
- (ii) wherein each switchable phase bit operates on a fraction of incident signal power, and
- (iii) wherein reflections from all parallel bits are recombined into a single signal reflected from the phase shifting device;
- and
- (b) an antenna, wherein the antenna is a single antenna or an array of antennas.
The system of claim 1, wherein the antenna is terminated with the phase shifting circuit such that the combined system reflects impinging waves with an altered phase, based on the state of the phase shifter circuit.
A system, comprising:
- (a) a device including a circuit configured to produce a phase shift in a reflected signal,
- (b) wherein a plurality of switchable phase bits are situated in parallel relative to one another within the device,
- (c) wherein each switchable phase bit operates on a fraction of incident signal power,
- (d) wherein reflections from all parallel bits are recombined into a single signal reflected from the phase shifting device, and
