Abstract:
A communications terminal includes an antenna structure and a metallic frame that includes at least one slot. The antenna structure includes an NFC antenna and a non-NFC antenna. The NFC antenna includes an NFC radiator, a first filtering unit, and an NFC circuit, and the non-NFC antenna includes a non-NFC radiator, a second filtering unit, and a non-NFC circuit. The NFC radiator and the non-NFC radiator are formed by the metallic frame of the communications terminal, and the entire non-NFC radiator is in the NFC radiator. The NFC circuit is coupled to the NFC radiator by using the first filtering unit, the non-NFC circuit is coupled to the non-NFC radiator by using the second filtering unit, the first filtering unit is configured to filter out a non-NFC signal, and the second filtering unit is configured to filter out an NFC signal.
