Abstract

The invention discloses a broadband small double-sided excitation earphone antenna design structure, relates to the field of earphones, and solves the problems that an earphone antenna in the prior art is generally a ceramic antenna for realizing a broadband, the process is complex, and the price is relatively high. The earphone is technically characterized by comprising an earphone shell, and an antenna mechanism and a feed mechanism which are arranged in the earphone shell, the antenna mechanism comprises a substrate, an antenna and a reflection excitation sheet. The substrate is arranged on the side surface of the reflection excitation sheet, and the antenna is arranged on the side surface of the substrate; the feed mechanism adopts a lumped feed mode, and an inductance adjusting circuit is matched to obtain an S parameter.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to a design structure of a broadband small double-sided excitation earphone antenna. Background technique [0002] With the development trend of more and more miniaturization of new mobile terminal products, the requirements for the appearance design of the antenna will also be refined and miniaturized, and the design requirements of high frequency bands must be met. The design of the Bluetooth headset antenna is generally limited to the shell or PCB board with a small space. In order to adapt to the miniaturization characteristics of the Bluetooth headset in the industry, the structure of the antenna is mostly used: serpentine structure, IFA structure and or inverted F deformation In order to meet the design requirements of miniaturization, the bandwidth of traditional antennas is generally relatively narrow. [0003] The existing design scheme is to use the FPC soft board as a ...
