Problems solved by technology
[0003] However, the inventors of the present invention have found that in the prior art, as the design of the mobile phone body with a metal frame or directly using a metal shell is widely used, and the existing mobile phones are getting thinner and thinner, the available area and height of the antenna are getting higher and higher. Therefore, the space reserved for RF switches, tuners, etc. is getting smaller and smaller, making it impossible for the antenna to switch freely in each frequency band
[0004] In addition, since the introduction of RF switches, tuners and other devices in the antenna will cause the loss of the antenna itself, even if the space reserved for the antenna in the mobile phone is sufficient, the introduction of too many RF switches and tuners will also bring damage to the antenna. More loss, thus affecting the standby time of mobile terminals such as mobile phones and affecting user experience

The invention relates to the communication field, and discloses an antenna system and a mobile terminal. The antenna system includes a circuit board with a feed point and a ground point, a housing for accommodating the circuit board, and an antenna radiation part that is in contact with the feed point and the ground point and is accommodated in the housing; wherein, the circuit board is provided with There is a USB interface, and the antenna radiating part is at least partly located directly above the USB interface; a metal tuning part is arranged between the antenna radiating part and the housing, and the metal tuning part is located directly above the USB interface to realize mid-high frequency tuning of the antenna radiating part . Compared with the prior art, the antenna system and mobile terminal provided by the present invention can widen the bandwidth of the required frequency band without introducing power consumption devices such as radio frequency switches and tuners, realize the coverage of the entire frequency band of communication, and reduce the complexity.
Description
technical field [0001] The invention relates to the communication field, in particular to an antenna system and a mobile terminal. Background technique [0002] With the rapid development of communication technology, LTE (Long Term Evolution, Long Term Evolution) requires antennas to cover wider and wider frequency bands, and low frequency (824-960MHz), intermediate frequency (1710-2170MHz) and high frequency (2300-2690MHz) The three frequency bands are more difficult to achieve, especially the medium and high frequencies (1710-2690MHz). In the prior art, the above-mentioned intermediate frequency and high frequency are usually realized by adding a radio frequency switch (RF switch) or a tuner (tuner) in different states, or through multiple antennas in frequency bands. [0003] However, the inventors of the present invention have found that in the prior art, as the design of the mobile phone body with a metal frame or directly using a metal shell is widely used, and the ex...
