Abstract

The invention discloses a dual-band antenna. The dual-band antenna comprises an antenna feed point, a feeder line, an antenna radiation unit and a metal ground, wherein the antenna feed point is of the position where the antenna is connected with a radio frequency circuit; the feeder liner is connected with the antenna radiation unit and the antenna feed point and is used for impedance matching; the antenna radiation unit is used for receiving and radiating electromagnetic waves; the antenna radiation unit comprises a first radiation unit and a second radiation unit which have different resonance frequencies; and the metal ground is a reference ground for the antenna. The bandwidth of the dual-band antenna disclosed by the invention can completely meet the requirements of a dual-band WLAN (wireless local area network) antenna; and in addition, the dual-band antenna has the advantages of low cost, easiness in adjustment of the size, small height and the like.

Description

technical field [0001] The invention relates to the communication field, in particular to a miniaturized dual-frequency antenna applying WLAN (Wireless Local Area Networks; wireless local area network) technology. Background technique [0002] With the development of wireless technology, WLAN technology is favored by more and more consumers, and is also valued by more and more products. The popular PAD (tablet computer or handheld computer) products, large-screen mobile phone products, and CPE (Customer Premise Equipment, customer terminal equipment) products all require better realization of "accessing the Internet through WLAN anytime, anywhere". Function. [0003] Among the various types of terminal products mentioned above, the antenna is an important part to realize the function of "accessing the Internet through WLAN anytime, anywhere", which directly affects the transmitting and receiving performance of the terminal products, that is, the speed and stability of Inter...
