平面アンテナ、非接触通信媒体、及び非接触通信媒体の製造方法
Document Type and Number:
Japanese Patent JP6776662
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a planar antenna which enables easy adjustment of the antenna resonance frequency, a non-contact communication medium with the planar antenna, and a method for manufacturing a non-contact communication medium with the planar antenna.SOLUTION: A planar antenna 10 comprises: a film base 11 made of a dielectric; an antenna coil 13 provided on a surface 11a of the film base 11; flat plate electrodes 14, 15 connected to the antenna coil 13 and disposed on the surface 11a of the film base 11; and flat plate electrodes 16, 17 disposed on a backside 11b of the film base 11 so as to be opposed to the corresponding flat plate electrodes 14, 15 in a thickness direction thereof with the film base 11 interposed therebetween. In the planar antenna 10, the flat plate electrodes 14, 16 and 15, 17 form capacitance parts, and the flat plate electrodes 14, 15, 16 are provided with respective wiring line electrodes 14a, 15a, 16a which enable capacitance adjustment of the capacitance parts.SELECTED DRAWING: Figure 2
