[0004] The existing mobile terminal antenna mainly has two realization structures: the slot antenna structure and the PIFA structure. Among them, the slot antenna structure is an antenna formed by slotting on a metal conductor plane. Because it can be expressed as a two-dimensional structure, it has a low profile. design advantages, but the slot antenna structure itself has a narrow bandwidth, which is relatively limited in broadband mobile terminal applications and ca

Abstract
The invention discloses a miniaturized mobile terminal antenna supporting dual-mode coexistence. The antenna comprises a dielectric substrate, a first feed network, a second feed network, a first antenna radiation unit and a second antenna radiation unit, and is characterized in that the first antenna radiation unit is positioned on the front side of the second antenna radiation unit; the first radiation unit and the second radiation unit are respectively composed of a plurality of metal conductors, and the metal conductors are sequentially connected and distributed on different surfaces of the dielectric substrate, so that the overall size of the antenna is reduced, and the space utilization rate of the dielectric substrate and the space utilization rate of the mobile terminal are improved; a stepped impedance structure is formed in the first antenna radiation unit and the second antenna radiation unit to achieve broadband and multiband characteristics of the antenna, a fixed decoupling network is used for reducing coupling between the first antenna radiation unit and the second antenna radiation unit, and most of metal conductors are in the same plane, so batch production can be realized by adopting a common PCB processing technology; and the antenna has the advantages of low profile and wide coverage frequency band.
Description
technical field [0001] The invention relates to a mobile terminal antenna, in particular to a miniaturized mobile terminal antenna supporting dual-mode coexistence. Background technique [0002] With the development of wireless communication technology, mobile terminals need to widely support 4G, 5G, Wi-Fi and other communication protocols and meet the increasing traffic demand. In the context of the fact that 5G is not yet widely used today, it is of great significance to configure mobile terminals to support dual-mode (such as 4G and 5G) simultaneous operation and realize carrier aggregation technology (Carrier Aggregation), thereby improving the transmission signal bandwidth. [0003] In order to effectively improve the potential of wireless communication capacity and spectrum utilization required by mobile terminals, multiple-input multiple-output (MIMO) multiple-antenna technology is widely used as a key technical means. Integrating more antenna units into a mobile ter...
