Abstract

The invention relates to an antenna array device applied to a 5G mobile terminal. The antenna array is composed of a plurality of magnetoelectric dipole antenna units. The antenna array forms end-fire radiation in the mobile terminal and overcomes the problem of narrow bandwidth of other antenna units. disadvantages. The novel antenna array of the present invention can be implemented in various forms, has a simple structure, occupies a small volume, and is conveniently integrated on the mobile phone board, and can be implemented in various technological forms such as surface mount method (SMT) or multilayer PCB integration as required. The antenna array has a compact structure and can be composed of antenna arrays with different numbers of units to meet the gain requirements. The antenna array occupies a small volume and has a wide antenna bandwidth, which can cover multiple 5G millimeter-wave frequency bands while maintaining a high antenna directional gain. And a stable radiation pattern, realize the high gain, beamforming, and beam scanning functions required for millimeter wave 5G communication, and are very easy to integrate into portable mobile terminal devices.

Description

technical field [0001] The present invention relates to the technical field of antennas, and more specifically, to an antenna array device applied to a 5G mobile terminal. Background technique [0002] Today, various new user needs and business forms have undergone tremendous changes: traditional voice and SMS services have been gradually eliminated by mobile Internet services; the development of cloud computing has placed the core of the business on the cloud, and the main link between the terminal and the network Transmission of control information, such a service form poses a great challenge to the traditional voice communication model; massive data connections brought by M2M / IoT, ultra-low latency services, ultra-high-definition, virtual reality services, and augmented reality services have brought Far exceeding the speed requirements of Gpbs, none of the existing 4G technologies can meet these business requirements. [0003] 5G is aimed at the human information society...
