Electronic device
View Patent ↗An electronic device includes a substrate, a coil that has a spiral shape and is provided on the substrate, and a conductive pattern that is provided inside of the coil, has optical reflectivity higher than that of a surface of the coil, and is divided into pieces.
1. An electronic device comprising:
a substrate;
a coil that has a spiral shape and is provided on the substrate; and
a conductive pattern that is provided inside of the coil, has an optical reflectivity that is higher than that of a surface of the coil, and is divided into pieces;
all the pieces of the conductive pattern being separate from the coil;
wherein the coil is structured with a plurality of coils that are spaced from each other in a longitudinal direction and are electrically connected to each other.
2. The electronic device as claimed in claim 1 , wherein the conductive pattern divided into pieces acts as a marker for localization.
3. The electronic device as claimed in claim 1 , wherein the conductive pattern divided into pieces acts as a marker for image recognition.
4. The electronic device as claimed in claim 1 , wherein each piece of the conductive pattern has one of round shape, rectangular shape, triangle shape, rhombic shape and elliptical shape.
5. The electronic device as claimed in claim 1 further comprising a capacitor provided on the substrate, wherein the conductive pattern is made of the same material as a lower electrode of the capacitor.
6. The electronic device as claimed in claim 1 , wherein the coil is made of a plated layer.
7. An electronic device comprising:
a substrate;
a coil that has a spiral shape and is provided on the substrate; and
a conductive pattern that is divided into pieces and provided in a range from a circumference to a distance of a radius of the coil, has an optical reflectivity higher than that of a surface of the coil, and acts as a marker for localization wherein the conductive pattern is for image recognition;
all the pieces of the conductive pattern are separate from the coil;
wherein the coil is structured with a plurality of coils that are spaced from each other in a longitudinal direction and are electrically connected to each other.
