Embodiment Construction

[0027] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all the same embodiments as the present disclosure. Rather, they are merely examples of apparatuses and methods in accordance with some aspects of the present disclosure as recited in the appended claims.

[0028] figure 1 is a schematic diagram of an antenna device according to an exemplary embodiment. In this illustration, the metal floor 103 of the circuit board in the terminal faces upwards. figure 2 is a schematic view of the circuit board in the terminal with the side opposite to the metal floor 103 facing up. image 3 is a perspective view of the antenna device.

Abstract

The disclosure relates to an antenna device and a terminal. The antenna device comprises a continuous metal frame, two ground connection points and a printed circuit board, wherein the continuous metal frame is connected with a metal floor of the printed circuit board via the two ground connection points, the metal floor is provided with a first slit and a second slit, the first slit is communicated with one end of the second slit, and the other end of the second slit extends to an edge of the metal floor; a back surface, positioned opposite to the metal floor, of the printed circuit board is provided with a feed microstrip line which is at least partially arranged opposite to the second slit. According to the antenna device and the terminal, while the metal frame of the terminal is used as an antenna, resonance oscillation can be increased via the slits of the circuit board, and bandwidth can be increased.

Description

technical field [0001] The present disclosure relates to the technical field of antennas, and in particular, to an antenna device and a terminal. Background technique [0002] With the development of terminal technology, people are increasingly using terminals such as mobile phones and tablet computers for work, social interaction, study, and entertainment. The metal frame can improve the appearance quality of the mobile phone and increase the firmness of the mobile phone, but the metal frame has a shielding effect on the built-in antenna of the mobile phone, so it is generally necessary to cut the metal frame. In the case of using a continuous metal frame as the antenna, if you need to further expand the bandwidth, you need to combine additional radiation elements, such as combining a monopole antenna or an inverted F antenna with a metal frame antenna to achieve greater bandwidth, but the monopole The sub-antenna and the inverted-F antenna need to rely on the bracket, and...
