A small rectenna including a thin conductive layer formed on a surface of
a dielectric substrate and a slot pattern arranged within the thin
conductive layer. The small rectenna for an RFID transponder includes: a
dielectric substrate; a thin conductive layer formed on a surface of the
dielectric substrate; a slot pattern configured within the thin
conductive layer so that the rectenna has an enhanced gain and a greater
operating bandwidth; and an inlet of an electronic chip including an ASIC
in the slot pattern.
