Reflective beamforming for performing chip-to-chip and other communications

A multi-chip device comprising:

• a first integrated circuit (IC) chip;
• and
• a second IC chip comprising:
• an antenna,
• a magnetic conductor configured to reflect and adjust a phase of a signal transmitted by the antenna to the first IC chip such that an effective radiation pattern of the antenna is reinforced in a direction of the first IC chip relative to a location of the second IC chip;
• and
• a regeneration circuit configured to amplify the signal transmitted by the antenna and reflected by at least one of a plurality of reflector power amplifiers.

A printed circuit board comprising:

• a first integrated circuit (IC) chip;
• and
• a second IC chip comprising an antenna and a plurality of reflector power amplifiers configured to reflect and adjust a phase of a signal transmitted by the antenna to the first IC chip such that an effective radiation pattern of the antenna is reinforced in a direction of the first IC chip relative to a location of the second IC chip,
• wherein at least one of the plurality of reflector power amplifiers comprises a magnetic conductor configured to reflect and adjust the phase of the signal transmitted by the antenna and a regeneration circuit configured to amplify the signal transmitted by the antenna and reflected by the at least one of the plurality of reflector power amplifiers.
