HANDHELD DEVICE HAVING MULTIPLE NFC READING DIRECTIONS |
| 摘要 |
A handheld device includes at least two NFC antennas provided with different RF transmission directions. The at least two NFC antennas are separated from each other and share one communication unit. In light of this, the handheld device exchange data with an external NFC device through the at least two NFC antennas to have more effective inductive coupling directions. |

1. A handheld device having multiple near-field communication (NFC) reading directions, comprising:
a communication unit having an input end and an output end for connection with a first circuit and a second circuit in parallel; a first NFC antenna mounted to the first circuit; and a second NFC antenna mounted to the second circuit and having a radio frequency (RF) transmission direction different from that of the first NFC antenna; wherein an equivalent inductance between the output end and the input end matches the communication unit. |
