Abstract

The invention provides an antenna structure which comprises a feed-in end, a first grounding end, a second grounding end, a first antenna and a second antenna. The first antenna comprises a first radiator and a second radiator which are sequentially connected with each other, the first radiator and the second radiator are connected with the feed-in end, the second antenna comprises a first radiation portion, a second radiation portion, a third radiation portion and a fourth radiation portion, the first radiation portion, the second radiation portion, the third radiation portion and the fourth radiation portion are sequentially connected with one another and form a semi-closed ring structure, the first radiation portion and the first radiator are arranged at intervals, the second radiation portion and the second radiator are arranged at intervals, and the first radiation portion and the fourth radiation portion are respectively connected with the first grounding end and the second grounding end. The antenna structure has the advantages that current signals are fed via the first antenna, the first antenna is coupled onto the second antenna, and accordingly wireless signals in various frequency bands can be received and transmitted by the antennas.

Description

technical field [0001] The present invention relates to a wireless communication device and its antenna structure, in particular to a wireless communication device covering multiple frequency bands and its antenna structure. Background technique [0002] In a wireless communication device, the antenna device used to transmit and receive radio waves to transmit and exchange radio data signals is undoubtedly one of the most important components in the wireless communication device. In recent years, the emergence of various communication systems and applications using different operating frequency bands has led to the development of antenna design towards antenna structures covering multiple system frequency bands. In order to ensure that the wireless communication device can perform signal transmission in various wireless communication systems using different operating frequency bands, the antenna device must be capable of transmitting and receiving signals of various frequenc...
