Near-field communication and ultra high frequency device

A device for near-field and ultra-high-frequency communication, the device comprising:

• an NEC near-field-communication antenna,
• a BLE ultra-high-frequency (UHF) antenna,
• a control unit comprising control means for controlling the ultra-high-frequency antenna and control means for controlling the near-field-communication antenna,
• a first carrier on which the NFC antenna is located,
• a second carrier on which the control unit is located,
• the first carrier and second carrier being located one above the other and connected by mechanical support pins,
• wherein the BLE UHF antenna is located on the first carrier and is connected to the control unit via:
• a first connection located on the first carrier, the first connection connecting the BLE UHF antenna to a mechanical support pin of the mechanical support pins, the mechanical support pin made of conductive metal, the mechanical support pin being perpendicular to the first carrier and the second carrier, and
• a second connection located on the second carrier, the second connection connecting the mechanical support pin to the control unit,
• wherein a first connection length of the first connection, and a second connection length of the second connection, a pin length of the mechanical support pin, and an antenna length of the BLE UHF antenna are designed such that the combined structure of the BLE UHF antenna, the first connection, the mechanical support pin, and the second connection has a total length to form a bidirectional BLE UHF antenna emitting an electromagnetic field at the same operating frequency as said BLE UHF antenna and having two components, a first component perpendicular to the first carrier and a second component which is parallel to the first carrier.
