Abstract
Flexible antennas for harvesting electromagnetic energy are described. The flexible antenna may be a far field antenna and may comprise a flexible substrate, a first metal layer disposed on one side of the flexible substrate, and a second metal layer disposed on an opposite side of the flexible substrate. The first and second metal layers may be connected through one or more vias. The first metal layer may be sized to capture electromagnetic energy at a frequency in an ISM band.

A far-field flexible energy harvesting antenna comprising:
- a flexible substrate having a first side and a second side opposite the first side;
- a first metal layer disposed in contact with the first side of the flexible substrate;
- a second metal layer disposed in contact with the second side of the flexible substrate;
- and
- one or more conductive vias electrically connecting the first metal layer with the second metal layer
- wherein the far-field flexible antenna is configured as a dual polarization antenna.
A far-field flexible energy harvesting antenna comprising:
- a flexible substrate having a first side and a second side opposite the first side;
- a metal layer disposed in contact with the first side of the flexible substrate;
- an electronic device disposed in contact with the second side of the flexible substrate;
- and
- one or more conductive vias electrically connecting the metal layer with the electronic device.
A method of harvesting energy with an antenna, comprising:
- capturing electromagnetic energy transmitted from a wireless power source using a first metal layer disposed in contact with a first side of a flexible substrate, the flexible substrate being positioned in a far-field region of the wireless power source;
- coupling the captured electromagnetic energy to a second metal layer disposed in contact with a second side of the flexible substrate via one or more vias connecting the first metal layer to the second metal layer;
- and
- powering an electronic device with the captured electromagnetic energy.
