Ke Hua

An antenna system and a mobile terminal implemented with the antenna system are provided. The mobile terminal has a metal frame and a system grounding. The antenna system has at least a first antenna module, a second antenna module, a third antenna module and a fourth antenna module. The first antenna module has a radiating body and a parasitic element coupled to the radiating body. The radiating body is configured to generate a main harmonic, and the parasitic element is configured to generate a parasitic harmonic. The first antenna module further has a first tuning circuit and a second tuning circuit. The antenna system has at least four operation modes. The antenna system of the present invention may achieve carrier aggregation of different LTE frequencies, and may be used as a MIMO antenna system.

Antenna system and mobile terminal implemented with the antenna system

An antenna module and a mobile terminal are provided. The mobile terminal has a metal frame and a system grounding spaced apart from the metal frame. The antenna module has a radiating body formed in the metal frame and a parasitic element coupled to the radiating body. The radiating body is configured for generating a main harmonic, and the parasitic element is configured for generating a parasitic harmonic. The antenna module further has a first tuning circuit connected in series between the radiating body and the system grounding, and a second tuning circuit connected in series between the parasitic element and the system grounding. The antenna system has at least four operation modes. The antenna system of the present invention may cover the LTE low, medium and high frequencies as a single antenna. A flexible and convenient method for tuning the antenna module is also provided.
