Problems solved by technology

[0003] Due to the limitation of installation space, most of the existing antennas need to be installed horizontally when in use, that is, the radiation arm of the antenna is parallel to the horizontal plane. In actual use, there will be blind spots at both ends of the radiation arm, and there is a defect that it is difficult to cover all directions. , especially can not achieve horizontal omnidirectional radiation, the use effect is poor

Abstract

The invention provides an antenna structure and a Bluetooth antenna. The antenna structure comprises a substrate, a first radiator and a second radiator, wherein the first radiator and the second radiator are arranged on the substrate; the substrate is provided with a first surface and a second surface which are opposite to each other; the first radiator comprises a first radiation body, a first radiation arm and a second radiation arm which are arranged on the first surface; the second radiator comprises a second radiation body, a third radiation arm and a fourth radiation arm which are arranged on the second surface; projections of the first radiation arm, the second radiation arm, the third radiation arm and the fourth radiation arm on the first surface form a closed or non-closed annular structure; the projection of the extension direction of the first radiation body and the projection of the extension direction of the second radiation body on the first surface are overlapped. Compared with an existing antenna, the antenna structure can achieve horizontal omnidirectional radiation, avoids a blind area in actual use, and is good in use effect.

Description

Technical field [0001] The present application relates to the field of antenna, in particular to antenna structure and a Bluetooth antenna. Background technique [0002] With the development of electronic technology, wireless electronics is booming and rapidly spread. Lightweight, miniaturization has become one of the development trends of the mainstream market, and for the antenna as a wireless electronic signal transmission tool, the need to meet the needs of the application environment is a key point of the antenna design while adapting to miniaturization. [0003] Due to the limit of installation space, most of the existing antennas require a level installation, that is, the radiation arm of the antenna is parallel to the horizontal plane, and there is a blind spot in both ends of the radiation arm during actual use, and there is a defect that is difficult to overwrite , Especially the horizontal full radiation, and the effect is poor. Inventive content [0004] The purpose ...
