Abstract

The invention relates to the technical field of wireless communication, in particular to a broadband miniature antenna for 5G mobile communication. The broadband miniature antenna comprises a metal patch, a planar equiangular spiral structure antenna array element, a broadband balun, a trapezoidal horn, a circular ring and reflection ground, wherein the outer wall of the trapezoidal horn, the inner wall of the circular ring and the reflection ground form a special-shaped reflection cavity. A novel antenna structure is provided for a 5G low-frequency band (below 6GHz); the circularly polarized broadband miniature antenna is designed by loading the circular metal patch, designing the unique special-shaped reflection cavity and the like; the dimension is simple and compact; and the broadband miniature antenna has good impedance and radiation characteristics within a 3GHz-6GHz working frequency band and can meet the requirements of a 5G large-scale MIMO antenna array.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a broadband miniaturized antenna for 5G mobile communication. Background technique [0002] Research on fifth-generation mobile communication (5G) technology has been in full swing around the world. The primary topic of the 2015 World Radio Conference (WRC-15) is to find spectrum resources for the fifth-generation mobile communication system in the frequency band below 6GHz. 5G frequency planning consists of low-frequency bands and high-frequency bands, of which low-frequency bands (below 6GHz) are still the core frequency bands of 5G systems due to good propagation characteristics, etc. The requirements of application scenarios; the high-frequency band (above 6GHz) is an important supplementary frequency band for 5G, which is mainly used to meet the needs of 5G enhanced mobile broadband services. Global consistency is an important basis for the general considerat...
