摘要： An antenna device includes a first antenna, a second antenna, a barrier, and a signal processing device. The first antenna transceives a first radio frequency (RF) signal in a first communication band, and the second antenna transceives a second RF signal in a second communication band. The first antenna includes a first radiator and a second radiator having a shape symmetrical to a shape of the first radiator. The second antenna includes third and fourth radiators having shape identical to those of the first and second radiators but having a size corresponding to the second communication band. The barrier includes a penetration region, and reflects the first and second RF signals. A center frequency of the second communication band is higher than a center frequency of the first communication band, and the first and second antennas are connected with the signal processing device through the penetration region of the barrier.

摘要： At least one example embodiment provides a near field communication (NFC) antenna matching network system connected to an NFC transceiver. The NFC antenna matching network system includes a matching circuit connected to first and second antenna terminals and to the NFC transceiver. The matching circuit is configured to match impedances of the NFC antenna network matching system and the NFC transceiver. The NFC antenna matching network system includes a plurality of NFC antennas connected in parallel with the first and second antenna terminals. Each of the NFC antennas includes a source coil and a resonance coil. The source coil is connected between the first antenna terminal and the second antenna terminal. The resonance coil is physically separated from the source coil and configured to exchange signals with the source coil via inductive coupling.
