Abstract

The invention discloses a built-in FM antenna and belongs to the antenna technology field. The built-in FM antenna is applied to a mobile terminal. The built-in FM antenna adopts a PCB form or a SMT form. Because the built-in FM antenna adopts the PCB form or the SMT form, the FM antenna of the PCB form and the FM antenna of the SMT form have small occupation spaces in the mobile terminal, installation is convenient and cost is low. By using the built-in FM antenna provided in an embodiment, a FM radio function can be satisfied, and simultaneously the spaces occupied in the mobile terminal can be saved. And the antenna possesses characteristics that the installation is convenient and cost is low.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a built-in FM antenna. Background technique [0002] FM (frequency modulation) radio function has been widely used in many portable electronic products, and has become a standard configuration function of audio, video and communication products. The civilian FM frequency band is 76MHz-108MHz, the longest wavelength is about 3 meters, and the corresponding receiving antenna size is about 1 meter. It is inconvenient to use and carry, and is gradually replaced by the built-in antenna. [0003] With the increasing integration of chips, mobile phones and other portable electronic products have diverse functions and miniaturization, and mobile phones need to integrate multiple antennas in a limited space. To achieve effective reception and transmission, the size of the built-in FM antenna needs to be large , the space requirements for the built-in FM antenna are large, and it is dif...
