Patent ID: 7671714

Claim:
A planar inductive component comprising: at least a first and a second concentric planar inductor, which include, respectively, a first electroconductive circular spiral pattern and a second electroconductive circular spiral pattern, the first electroconductive circular spiral pattern having a first end point and a second end point, and the second electroconductive circular spiral pattern having a first end point and a second end point, characterized in that the first electroconductive circular spiral pattern that belongs to the first concentric inductor, and the second electroconductive circular spiral pattern that belongs to the second concentric inductor are interlaced and are respectively patterned in a radius that increases from an inner end to an outer end; the first end point and the second end point of the first electroconductive circular spiral pattern are electroconductively interconnected, and the first electroconductive circular spiral pattern is interrupted at the outside by a narrow slit so as to form a first electroconductive contact and a second electroconductive contact on either side of the interruption; the first end point and the second end point of the second electroconductive circular spiral pattern are electroconductively interconnected, and the second electroconductive circular spiral pattern is interrupted at the outside by a narrow slit so as to form a first electroconductive contact and a second electroconductive contact on either side of the interruption.
