Abstract

The invention relates to a terminal. The terminal comprises a metal shell, and a circuit board, a filter and a changeover switch which are arranged in the metal shell. The metal shell is provided with at least one slot antenna. At least one slot antenna comprises at least two pairs of feed points. The two pairs of feed points comprise a main feed point and a ground feed point. All the main feed points and all the ground feed points are respectively connected with the edges of the two ends of the slots. The filter is arranged on the circuit board, and the filter is electrically connected with the at least two pairs of feed points and the circuit board. The changeover switch is arranged on the circuit board and electrically connected with the at least two pairs of feed points, the filter and the circuit board. The changeover switch is used for switching of different feed points so as to conducting each feed point and the circuit board. The terminal has advantages of simple structure and accurate control of resonant frequency.

Description

technical field [0001] The present invention relates to the field of electronic communication, in particular to a terminal. Background technique [0002] At present, the antenna design of the all-metal shell terminal usually adopts the method of adding a separation slot on the metal shell, opening two slits on the metal shell, and separating the metal shell into three parts, which are the first part, the second part and the third part in turn. Part, design one or two antennas on the first part, design one antenna on the third part, and then separate the first part and the third part by grounding the second part. However, this kind of design scheme can generally only design about three antennas, and it is difficult to meet the global positioning system (GPS), wireless network (WIFI), Bluetooth (BT), and diversity antennas required by current 4G and / or 5G terminals. , near-field communication (NFC) antennas and other multi-antenna requirements, and if you want to increase mul...
