Title:
LOOP ANTENNA AND MANUFACTURING METHOD OF THE SAME
Document Type and Number:
Japanese Patent JP2016129310
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a loop antenna that prevents short-circuit by uniformly electrolytic plating across an entire antenna without influencing on inherent characteristic impedance.SOLUTION: A loop antenna (1) includes: copper, formed in a spiral shape, having a corner part (6); electrolytic copper formed by electrolytic plating on a surface of the copper; and a widening part (7) capable of being in contact with a rack pin (electrode) used for electrolytic plating by making a neighborhood of the corner part (6) to be wider than the other part.SELECTED DRAWING: Figure 1
