Embodiment Construction

[0014] see figure 1 , a preferred embodiment of the present invention provides an antenna structure 100, which is applied in wireless communication devices (not shown) such as mobile phones and tablet computers, and is used for sending and receiving wireless communication signals.

[0015] The antenna structure 100 includes a circuit board 10 and an antenna 20 . The circuit board 10 is the main board of the wireless communication device. The antenna 20 is formed on the circuit board 10 by printing, the manufacturing process is simple and easy to produce, and the manufacturing cost can be reduced.

[0016] The antenna 20 includes a ground portion 21 , a feeding portion 22 , a connection portion 23 , a first resonant portion 24 and a second resonant portion 25 . The feed-in portion 22 is extended from the ground portion 21 with a gap 26 formed therebetween. The first resonant portion 24 and the second resonant portion 25 are connected to the ground portion 21 and the feed-in p...

Abstract

The invention provides an antenna structure. The antenna structure comprises a circuit board and an antenna which is formed on the circuit board. The antenna comprises a grounding part, a feed-in part, a connecting part, a first resonance part and a second resonance part, wherein the grounding part and the feed-in part are respectively used for grounding and signal feed-in. The feed-in part is formed by extending the grounding part. A gap is surrounded by the feed-in part and the grounding part. The first resonance part and the second resonance part are connected with the grounding part and the feed-in part through the connecting part. A first interval is surrounded by the first resonance part, the connecting part and the grounding part. A second interval is surrounded by the second resonance part, the connecting part and the feed-in part. By adjusting the size of the first interval and the gap, the first resonance part is used for transmitting and receiving the signal of a first working frequency band. By adjusting the size of the second interval, the second resonance part is used for transmitting and receiving the signal of a second working frequency band.

Description

technical field [0001] The invention relates to an antenna structure, in particular to a dual-frequency antenna structure supporting Bluetooth and WiFi functions. Background technique [0002] With the rapid development of communication systems, the functions of wireless communication devices such as mobile phones and tablet computers are becoming more and more diversified. Bluetooth and WiFi functions have become one of the basic configurations of wireless communication devices. Correspondingly, the wireless communication device needs to have an antenna structure supporting Bluetooth and WiFi functions. [0003] The existing antenna structure generally includes a circuit board and an antenna. The antenna includes a grounding part and a feeding part for grounding and signal feeding respectively. Since wireless communication devices are becoming lighter and thinner, the antenna structure not only supports the above functions, It is also required that the above-mentioned circ...
