Abstract

The invention relates to a 5G application-oriented shared two-unit microstrip MIMO antenna based on a radiation structure, and the antenna comprises three layers of dielectric plates, i.e., a first dielectric plate, a second dielectric plate and a third dielectric plate, which are sequentially stacked from the top to the bottom; the dielectric plates are the same in size and material, an incomplete circular metal patch is arranged on the upper surface of the first dielectric plate, an arc-shaped notch is formed in the edge of the circular metal patch, and a first metal patch and a second metalpatch are distributed among the first dielectric plate, the second dielectric plate and the third dielectric plate; the invention relates to the broadband microstrip antenna. By adopting an aperturesharing technology, miniaturization of the antenna structure is realized; the miniaturization degree can reach (50 + / -0.5)%, the common bandwidth of the two unit antennas can reach (13.4 + / -0.1)%, theantenna has the characteristics of unidirectional radiation and low cost, and by adopting a coupled feeding technology, the port isolation degree and the far-field radiation gain between the unit antennas are improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a 5G application-oriented shared two-element microstrip MIMO antenna based on a radiation structure. Background technique [0002] Mobile communication technology is one of the fastest-growing technical fields today. After the development of the previous 4 generations of mobile communication, the 5G wireless communication technology that has landed can bring a revolutionary impact on people's production and life, and will trigger a new generation. The industrial revolution led by information technology. As long as wireless communication is involved, there must be a device in the system, that is, the antenna device, and the performance of the antenna device also has an important impact on the performance of the entire wireless mobile communication system. Especially in 5G mobile smart devices, there are more antennas. Of course, the most important thing...
