Problems solved by technology
[0002] At present, more and more antennas are used in smart watches. Due to the limited installation space of smart watches, the antennas of most smart watches are single-band antennas, but obviously single-band antennas can no longer meet the requirements of diversified functions of smart watches; In this case, the smart watch uses multiple antennas to achieve the purpose of multi-band coverage, but the existence of the antenna occupies a larger space volume, and the isolation between multiple antennas is difficult to improve in the small installation space of the watch. , the follow-up circuit is relatively complex, so the current antenna cannot meet the requirements of multi-band coverage, simple structure, and small footprint

Embodiment approach
[0052] In one embodiment, the grounding point 110 may be fixedly connected to a metal shell (not shown), and the metal shell is used as a common electrode to achieve grounding. In this embodiment, a planar electrode with a width of 30 mm and a length of 40 mm is provided as a model of the ground electrode 1 . A plastic casing (not shown) with a dielectric constant of 2.2 is arranged around the ground electrode 1, and the antenna 100 is supported by the plastic casing, and the feed point 120 can be electrically connected to the circuit board (not shown). The microstrip line is used to connect the AC signal of the feed source provided on the circuit board through the microstrip line to realize the feed output to the antenna 100 . The grounding point 110 , the feeding point 120 , the first radiating strip 130 , the first radiating arm 140 and the first connecting portion 160 can be arranged on a thin metal sheet, and can be installed on a plane at the same time. The grounding po...

The invention discloses an antenna and a terminal. The antenna comprises a grounding electrode; a feed source; a first radiation belt of which the two ends in the length direction are respectively connected with the grounding electrode and the feed source; a first radiation arm which is mutually close to the first radiation belt with the spacing distance kept between the first radiation arm and the first radiation belt so as to form a first capacitor; and a first connecting part which is connected between the first radiation belt and the first radiation arm. Therefore, inductive impedance of the antenna is enabled to be matched with capacitance impedance so that performance of the antenna can be enhanced, coverage of multiple frequency bands can be realized, the structure is simple and space occupation is low.
Description
technical field [0001] The invention relates to the field of antennas, in particular to an antenna and a terminal. Background technique [0002] At present, more and more antennas are used in smart watches. Due to the limited installation space of smart watches, the antennas of most smart watches are single-band antennas, but obviously single-band antennas can no longer meet the requirements of diversified functions of smart watches; another In this case, the smart watch uses multiple antennas to achieve the purpose of multi-band coverage, but the existence of the antenna occupies a larger space volume, and it is difficult to improve the isolation between multiple antennas in the small installation space of the watch. , the follow-up circuit is relatively complex, so the current antenna cannot meet the requirements of multi-band coverage, simple structure, and small footprint. Contents of the invention [0003] The object of the invention is to provide an antenna and term...
