Abstract

The invention discloses a tri-band mobile phone antenna. The tri-band mobile phone antenna includes a double-sided substrate, a cuboid which is located at the perigon of the upper surface of the double-sided substrate and is integrally connected with the double-sided substrate, a first strip which winds the cuboid along the upper surface and side surfaces of the cuboid, a second strip which winds the cuboid in a bent manner along the side surfaces of the cuboid, a feeding part, a grounding end and a grounding groove; the grounding groove is in the shape of a rectangle; and an inverted L-shaped strip matched with the grounding groove is arranged in the grounding groove. The tri-band mobile phone antenna can realize tri-band communication, and has the advantages of small size, simple structure and low cost.

Description

technical field [0001] The invention relates to the technical field of mobile phone antennas, in particular to a mobile phone antenna suitable for 4G (LTE) communication. Background technique [0002] In recent years, with the continuous development of mobile communication technology and the popularization of 4G-LTE technology, my country's mobile communication industry has put forward new requirements: while meeting the requirements of 4G-LTE communication, it must also be compatible with existing 2G, 3G standard compatible. As one of the most important components in the field of wireless communication, antennas are inevitably multi-frequency, so that they can support different application requirements and achieve system compatibility. With the current high integration of smartphones, in order to achieve more functions, the area reserved for antennas in mobile phones is getting smaller and smaller, which will inevitably make the design of mobile phone antennas more difficul...
