Novel MIMO millimeter wave oblique polarization antenna for 5G

Abstract

The invention relates to the technical field of communication, in particular to a novel MIMO millimeter wave oblique polarized antenna for 5G, which comprises an antenna body and a PCB substrate. The antenna body is arranged on the PCB substrate and consists of a positive 45-degree polarized antenna and a negative 45-degree polarized antenna which are symmetrical; and each of the positive 45-degree polarized antenna and the negative 45-degree polarized antenna comprises a feed input assembly, an energy transmission assembly and an energy radiation assembly. The antenna can realize positive and negative 45-degree oblique polarization performance, is simple in structure and stable in performance, can enable the antenna structure to be integrated, is simple in antenna processing, and facilitates the batch production of the antenna.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a novel MIMO millimeter wave obliquely polarized antenna for 5G. Background technique [0002] With the vigorous development of 5G MIMO technology, research on the millimeter wave frequency band has become one of the current hotspots, with huge application potential. The 5G wireless communication system puts forward higher requirements for the antenna. The specific characteristics of an antenna with superior performance are high gain, miniaturization, low sidelobe, and convenient processing. Substrate Integrated Waveguide (SIW) is an antenna structure proposed in recent years. It overcomes the shortcomings of traditional waveguides that cannot be seamlessly connected with integrated circuits, and inherits the advantages of high gain and large power capacity of traditional waveguides. Electromagnetic leakage is lower compared to microstrip. In the field of microwave, espe...
