Abstract

The invention discloses a miniature antenna unit capable of controlling wave beam widths and a large-scale antenna array capable of controlling wave beam widths. The miniature antenna unit comprises a radiation plate, a dielectric layer, a micro-strip slot antenna substrate and a reflecting cavity; the dielectric layer is arranged between the radiation plate and the front surface of the micro-strip slot antenna substrate; the dielectric constant of the dielectric layer is greater than that of air; the micro-strip slot antenna substrate is a high-dielectric-constant substrate; and the dielectric constant of the high-dielectric-constant substrate is greater than 3.5; and the reflecting cavity is formed in the reverse surface of the micro-strip slot antenna substrate. The miniature antenna unit and the large-scale antenna array are small in size, and the wave beam widths can be controlled by changing the dielectric constant of the dielectric layer in the antenna unit and the dielectric constant of the high-dielectric-constant substrate.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a miniaturized antenna unit and a large-scale antenna array with controllable beam width. Background technique [0002] With the rise of smart terminals and the enrichment of wireless data application services, the number of data users in wireless communication systems has increased significantly, and data content is no longer limited to traditional text or images. The increasing demand for wireless network traffic has led to explosive growth. According to the forecast of market institutions, wireless data services will increase by 500-1000 times in the next ten years, with an average annual growth rate of 1.6-2 times, which puts forward higher requirements on the network capacity of wireless communication systems. There are many ways to improve the network capacity of wireless communication systems, mainly including improving spectrum efficiency, increasing network...
