Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] Such as figure 1 As shown, an antenna system 100 includes a seamless metal ring 101 and a circuit board 102 disposed in an area surrounded by the metal ring 101 . The metal ring 101 includes two relatively long sides 101a, a relatively short side 101b connected to the two long sides 101a and a reinforcing rib 110 connecting the two long sides 101a. The entire metal ring 101 is made of amorphous alloy. Amorphous alloys have higher strength than ordinary metals, and the size effect of strength is small. The elasticity of amorphous alloys is also better than that of ordinary metals, the bending deformation can reach more than 50%, and the hardness and toughness are also high. In addition, amorphous alloys are not restricted by grain boundaries, and because of their good fluidity, they can be molded at one time to facilitate the formation of ribs....

The invention provides an antenna system, which includes a closed metal ring and a circuit board arranged in the area surrounded by the metal ring. The circuit board includes a feeding part and a grounding part, and the metal ring is provided with at least two first grounding points short-circuited with the grounding part, and the part of the metal ring between the two first grounding points is the radiator of the antenna system . The radiating body is provided with a first feeding point electrically connected to the feeding part, a second feeding point arranged at intervals from the first feeding point and electrically connected to the feeding part and the grounding part, and connected to the ground. Second ground point for partial electrical connection. The antenna system further includes a matching circuit for controlling only one of the first feeding point and the second feeding point to be connected to the feeding part. The antenna system of the present invention realizes the metal frame antenna design without gaps through multi-point feeding and matching circuits, and only uses the same radiator on the metal ring to achieve full frequency band coverage of low frequency, intermediate frequency and high frequency bands. The antenna size smaller.
Description
technical field [0001] The invention relates to the field of consumer electronics, in particular to an antenna system for portable electronic equipment. Background technique [0002] With the development of portable electronic devices towards thinner and lighter, the traditional antenna structure can no longer meet consumers' ultimate pursuit of light and thin portable electronic devices. In order to adapt to the development of thinner and lighter portable electronic devices, portable electronic devices with all-metal back shells have appeared, and metal frame antenna structures have also emerged as the times require. [0003] However, the metal frame antenna structure in the related art requires slots on the metal frame, and the metal frame antenna radiates or receives electromagnetic energy through the slots or openings. The cracks or openings on the metal frame will affect the overall consistency of the all-metal back shell, so the metal frame antenna structure without c...
