Problems solved by technology

However, due to the thinning and thinning of wireless communication devices, the size of the antenna structure is also compressed, and the bandwidth is limited. Therefore, in the low-frequency part, the transmission requirements of the United States and Europe cannot be met at the same time.

Abstract

The invention discloses a portable electronic device and an antenna structure thereof. The antenna structure comprises a first radiator, a second radiator, a second coupling part and a switching circuit; the first radiator comprises a feed-in part and a first radiator body; the second radiator comprises a first coupling part, a second radiator body and a grounding part; the first coupling part is connected with a first end part of the second radiator body; the grounding part is connected with the second radiator body; and the first radiator body is partly located between the first coupling part and the second coupling part. When the antenna structure is in a first mode state, a pathway is formed between the second radiator body and the second coupling part by the switching circuit; and when the antenna structure is in a second mode state, an open way is formed between the second radiator body and the second coupling part by the switching circuit.

Description

technical field [0001] The present invention relates to an antenna structure, in particular to an antenna structure capable of changing operating frequency bands. Background technique [0002] At present, for a single wireless communication standard, there are still different operating frequency bands in different regions. Taking the LTE (Long Term Evolution) communication specification as an example, the operating frequency bands in the United States are 704~960MHz and 1710~2170MHz. The operating frequency bands in Europe are 791~960MHz and 1710~2170MHz. However, due to the thinning of wireless communication devices, the size of the antenna structure is also compressed, and the bandwidth is limited. Therefore, in the low frequency part, the transmission requirements of the United States and Europe cannot be met at the same time. Contents of the invention [0003] The present invention provides an antenna structure to solve the problems in the prior art, including a firs...
