Abstract

An antenna structure includes a metal housing, a first feed portion, a first ground portion, a second ground portion, and a radiator. The metal housing includes a front frame, a backboard, and a sideframe. The side frame defines a slot and the front frame defines a gap. The metal housing is divided into at least a long portion and a short portion by the slot and the gap. One end of the first feedportion is electrically connected to the long portion, and the other end is electrically connected to the backboard. One end of each of the first ground portion and the second ground portion is electrically connected to the long portion, and the other end of each of the first ground portion and the second ground portion is electrically connected to the backboard for grounding the long portion. The radiator is electrically connected to the backboard, and is spaced apart from and coupled to the short portion. The backboard of the antenna structure forms an all-metal structure, and the case thatthe integrality and beauty of the backboard are affected due to arrangement of the slot, the groove or the gap can be effectively avoided. The invention also provides a wireless communication devicehaving the antenna structure.

Description

Technical field [0001] The invention relates to an antenna structure and a wireless communication device with the antenna structure. Background technique [0002] With the advancement of wireless communication technology, wireless communication devices continue to develop toward a light and thin trend, and consumers have higher and higher requirements for product appearance. Since metal casings have advantages in appearance, mechanical strength, and heat dissipation effect, more and more manufacturers have designed wireless communication devices with metal casings, such as backplanes, to meet consumer needs. However, the metal shell easily interferes with and shields the signal radiated by the antenna disposed therein, and it is not easy to achieve a wide-band design, resulting in poor radiation performance of the built-in antenna. Furthermore, the backplane is usually provided with slots and break points, which will affect the integrity and aesthetics of the backplane. Summary...
