The present invention provides an antenna structure and a mobile terminal. The antenna structure includes: an antenna radiator; a ground plate, a clearance area is formed between the ground plate and the antenna radiator; a signal source, a first end of the signal source is connected to the ground plate; a first capacitor, The first end of the first capacitor is connected to the second end of the signal source, and the second end of the first capacitor is connected to the antenna radiator; a first impedance matching network, the first impedance matching network are respectively connected with the antenna radiator and the ground; wherein, the antenna structure generates at least two resonance modes including a first resonance mode, a second resonance mode and a third resonance mode, the first resonance mode The second resonant mode resonates at one-quarter wavelength or three-quarter wavelength of the second frequency band. The present invention can meet the multi-CA requirement of simultaneously supporting multiple frequency bands.
Description
technical field [0001] Embodiments of the present invention relate to the field of electronic technology, and in particular, to an antenna structure and a mobile terminal. Background technique [0002] In order to increase the Internet access rate of mobile terminals, a multi-carrier aggregation (Carrier Aggregation, CA) technology is popularized. For example, B39 (1.88GHz~1.92GHz) frequency band + B41 (2.5GHz~2.69GHz) frequency band "IF + HF" CA combination, B5 (0.824GHz~0.894GHz) frequency band + B3 (1.71GHz~1.88GHz)+ B1 (1.92GHz~2.17GHz) "low frequency + intermediate frequency" CA combination. Here, the low frequency / intermediate frequency / high frequency refer to frequency bands of 0.824GHz˜0.96GHz / 1.71GHz˜2.17GHz / 2.3GHz˜2.7GHz, respectively. In the future, operators may also launch "low frequency + intermediate frequency + high frequency" multi-CA combination, such as B5+B3+B7. Multi-CA technology requires mobile terminal antennas to support multiple frequency bands a...
