ANTENNA AND PORTABLE ELECTRONIC INSTRUMENT FOR USE IN NEAR FIELD COMMUNICATION

摘要

Disclosed is an NFC antenna that facilitates a touch operation of a portable electronic instrument. An NFC antenna includes insulating substrates and an antenna coil having a front surface pattern and a back surface pattern formed on antenna surfaces that are present on the same planes. The insulating substrates are molded into an L shape together with a magnetic sheet sandwiched therebetween. The antenna coil is also arranged in the L shape in a similar manner. When the NFC antenna is arranged at a corner of a smart phone, a coil opening faces to a position of a touch corner. NFC can be started in a short time by a touch operation using the touch corner.

主权项

1. An antenna, comprising:
an insulating substrate provided with a bent portion in which an antenna surface is bent at a predetermined angle on a same plane; and a loop-like antenna coil including a coil pattern formed on the antenna surface so as to be bent at the predetermined angle, the antenna coil being provided with an inlet/outlet port of a crossing magnetic flux on a side surface of the insulating substrate.
