Problems solved by technology

[0002] At present, the volume of wireless devices is getting smaller and smaller, and the space for built-in antennas is getting smaller and smaller. The conventional antenna forms are generally inverted L-shaped and inverted F-shaped antennas. It is difficult to achieve multi-band effects in a limited space, and the antenna is also less efficient

Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0041] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a multi-frequency built-in antenna and an antenna terminal. The multi-frequency built-in antenna comprises a multi-frequency built-in antenna and an antenna radiation arm, wherein the multi-frequency built-in antenna comprises a circuit board, an antenna feeding point is arranged on the circuit board, one end of the antenna radiation arm is electrically connected with the antenna feeding point, the antenna radiation arm is folded and wired to form a low-frequency unit, and the other end of the antenna radiation arm and an adjacent part are automatically coupled to forma first high-frequency resonant unit. With the multi-frequency built-in antenna disclosed by the technical scheme, the low-frequency and high-frequency design of the antenna is achieved on the premisethat relatively small space volume is met, and the multi-frequency built-in antenna has the beneficial effects of multiple frequency bands and high efficiency.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a multi-frequency built-in antenna and a wireless terminal. Background technique [0002] At present, the volume of wireless devices is getting smaller and smaller, and the space for built-in antennas is getting smaller and smaller. The conventional antenna forms are generally inverted L-shaped and inverted F-shaped antennas. It is difficult to achieve multi-band effects in a limited space, and the antenna is also less efficient. [0003] Therefore, it is urgent to design a miniaturized, high-efficiency multi-band antenna in a small space to meet the development requirements of wireless devices. Contents of the invention [0004] The main purpose of the present invention is to propose a multi-frequency built-in antenna, which aims to reduce the volume of the antenna, and at the same time realize the effect that the antenna has multiple frequency bands and high e...
