Abstract
A pixel structure and an image sensor are provided, to improve photoelectric conversion efficiency under a weak light condition and resolve a problem that an image generated in weak light is dim. The pixel structure includes a metallic ground plane, and a substrate unit cell located on the metallic ground plane. The pixel structure further includes a nano antenna unit that is located on the substrate unit cell and that includes one or more nano antennas, each of the one or more nano antennas corresponding to one optical band and including M parts A nano gap is formed between the M parts, a metal-insulator-metal diode is formed at the nano gap, and M is a multiple of 2. The pixel structure further includes a packaging unit that covers the nano antenna unit. The image sensor includes a plurality of pixel structures.
