Generally, the lower portion of the monopole antenna must be hollowed out, so that the antenna must be designed with an antenna position for accommodating the antenna. Meanwhile, the metal layer of the monopole antenna cannot be used as a ground plane or a ground terminal, and the monopole antenna is easily affected by peripheral components, such as a power terminal and a signal transmission terminal, so that the performance of the antenna is easily interfered. In addition, the planar inverted F antenna is a major antenna design form at present, and its basic architecture includes a metal Patch (Metallic Patch), a ground plane, a Shorting Plate (Shorting Plate), and a Coaxial Feed (Coaxial Feed). Although the planar inverted F antenna has a low profile and a light volume, the minimum height of the planar inverted F antenna is only about 7mm, and thus the thickness of the product cannot be effectively reduced. In terms of the requirement, a bluetooth antenna is designed, so that the antenna has enough space and height, the space utilization rate is improved, the performance of the antenna is effectively prevented from being interfered, or the effects of large-scale circuit structure and modification of space structure caused by the addition of an antenna support are avoided, and the bluetooth antenna becomes an irresistible issue in market application.
