Title:
TERMINAL HOUSING AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2018/058300
Kind Code:
A1
Abstract:
Provided are a terminal housing and a terminal, which relate to the technical field of terminals. The terminal housing comprises: a back cover (11), an antenna bracket (12) arranged in the inner side of the back cover (11), and a PCB board (13) arranged inside the terminal housing. The antenna bracket (12) is located between the back cover (11) and the PCB board (13) and is provided with an antenna unit. The antenna unit comprises a first branch (121) and a second branch (122). A first via hole (1211) is provided in the first branch (121) and a second via hole (1221) is provided in the second branch (122). A routing wire (131) is provided in the PCB board (13) at a position corresponding to the first via hole (1211) and the second via hole (1221). A variable capacitor (14) is connected in series with the routing wire (131). A first end of the routing wire (131) is connected to the first via hole (1215) and a second end of the routing wire (131) is connected to the second via hole (1221). The variable capacitor (14) is provided between the two branches (121, 122) of the antenna unit, and thus the manner of current coupling of an antenna can be changed to a certain extent by adjusting the capacitance of the variable capacitor (14), realizing tuning of a terminal antenna within a wide frequency range. Accordingly, the terminal has a good tuning capability.
