Abstract

The invention discloses a mobile phone antenna for 4G communication. A mobile phone comprises the antenna and a substrate, and the antenna is arranged on the substrate and comprises a coupled feeding metal sheet, an L-shaped inductance metal sheet and a radiation metal sheet which are sequentially connected. According to the mobile phone antenna, by adopting the planar monopole antenna and two main radiation branches, two resonant modes are generated at the high frequency, therefore, a relatively wide frequency band can be formed at the high frequency by adjusting the positions of the two resonant modes to enable the resonant modes to be close, and miniaturization, multiband and broadband of the antenna are achieved. The mobile phone antenna for 4G communication is widely suitable for the field of wireless communications antennae.

Description

technical field [0001] The invention relates to the field of wireless communication antennas, in particular to a mobile phone antenna applied to 4G communication. Background technique [0002] With the development of data communication and multimedia business needs, the fourth generation of mobile communication that meets the needs of mobile data, mobile computing and mobile multimedia operations has begun to emerge. 4G communication is recognized by the China Internet of Things School-Enterprise Alliance because of its ultra-high data transmission speed. Known as the well-deserved "high-speed dialogue" between machines. However, the low frequency of ultra-wideband antennas is limited by the size of the antenna, so how to design an antenna with a wide enough bandwidth in a specific space is a major problem in the industry. On the other hand, the rapid development of modern integrated circuit technology and technology makes electronic products smaller and smaller. As the ter...
