Terminal with metal frame antenna

Abstract

The invention provides a terminal with a metal frame antenna. The terminal comprises a dielectric substrate, a metal floor and a metal frame, wherein a first gap, a second gap, a third gap and a fourth gap which do not communicate with one another are formed in the edge of the metal floor; a first breakpoint, a second breakpoint, a third breakpoint and a fourth breakpoint are correspondingly arranged at one end, connected with the first gap, the second gap, the third gap and the fourth gap, of the metal frame; the second surface of the dielectric substrate is provided with a first matching network, a second matching network, a third matching network and a fourth matching network; the first matching network, the second matching network, the third matching network and the fourth matching network are in one-to-one corresponding feed connection with one end of the first gap, one end of the second gap, one end of the third gap and one end of the fourth gap. According to the terminal provided by the invention, the size of the clearance space required by the antenna in mobile terminals such as a mobile phone is reduced, and the development requirement of the clearance area of the mobile terminals such as the mobile phone under the narrower trend is met.

Description

technical field [0001] The present application relates to the technical field of communication equipment, and in particular to a terminal with a metal frame antenna. Background technique [0002] With the development of smart terminal technology, mobile terminals such as mobile phones carry more and more information transmission functions, and one-to-many link scenarios of a single communication terminal are also very common, such as mobile phones and multiple base stations, positioning equipment and multiple satellites , routing equipment and multiple data terminals, etc. Therefore, in order to adapt to the above usage scenarios of mobile terminals such as mobile phones, mobile terminals such as mobile phones have higher and higher requirements on the performance of their antennas. [0003] In recent years, mobile terminals such as full-screen mobile phones have become more and more popular among users because the ultra-high screen-to-body ratio brings users a better visua...

AI Technical Summary

Problems solved by technology

However, at present, the antenna structure of mobile terminals such as mobile phones requires a width of more than 3 mm in the clearance area. When this type of antenna structure is applied to mobile terminals such as mobile phones with relatively small clearance areas, the area occupied by the terminal antenna is reduced (shrinking mobile phones, etc.) The space occupied by the antenna of the mobile terminal), the Q value of the antenna increases, so that the mobile terminal antenna such as a mobile phone not only narrows the bandwidth, but also deteriorates the efficiency, especially in the low frequency band
