Two-unit folding short-circuit monopole MIMO antenna of broadband loaded circular patch

Abstract

A two-unit folding short-circuit monopole MIMO antenna of a broadband loaded circular patch comprises a dielectric substrate, a Y-shaped metal isolator and two antenna units of the same structure arearranged on the upper surface of the dielectric substrate, and two connected rectangular metal patches are arranged on the lower surface of the dielectric substrate. The two rectangular metal patchesare arranged along the two adjacent edges of the dielectric substrate, and the end parts of the two rectangular metal patches are overlapped and connected to form a grounding plate of the antenna; each antenna unit comprises a first vertical radiation arm, a horizontal radiation arm and a second vertical radiation arm which is connected to a rectangular metallized via hole from the other end of the horizontal radiation arm, the second vertical radiation arm is connected with the grounding plate of the antenna through the rectangular metallized via hole, a circular loaded metal patch is arranged on the horizontal radiation arm, and the two antenna units are separated by the Y-shaped metal isolator. According to the invention, the high-efficiency radiation of the antenna is realized, the resonance bandwidth of the antenna is expanded, and the isolation degree between the unit antennas is increased.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a two-unit folded short-circuit monopole MIMO antenna with a broadband loading circular patch, which is suitable for 5G wireless communication systems. Background technique [0002] Although the fifth-generation mobile communication technology and the fourth-generation mobile communication are only optimized in three aspects: data transmission rate, network capacity and delay. However, 5G mobile communication supports a user experience rate of 0.1-1Gpbs, a connection density of one million per square kilometer, a terminal delay of milliseconds, a traffic density of 10Tbps per square kilometer, a mobile performance of more than 500km / h and a 20Gbps peak rate. Compared with the 4G mobile communication system, the above indicators are fundamental value changes. [0003] In the past, the upgrading of wireless mobile communication technology was mainly to improve th...
