An antenna device with multiple boundaries and its reflector

Abstract

The invention provides a base station antenna reflecting board. The reflecting board is characterized by comprising a reflecting surface and at least two groups of side edges arranged on the reflecting surface, a first group of side edges is arranged at edges of two sides of the reflecting surface, a second group of side edges is arranged between the side edges of the first group, each group of side edges comprises two side edges which are mutually parallel and symmetrically distributed relative to a central axis of the reflecting surface, and an interval exists between any adjacent side edges. Simultaneously, an antenna device with multiple boundaries, which utilizing the antenna reflecting board, is provided, by means of multiple radiation side edge technology, the antenna beam bandwidth is widened, the convergence of the beam width is improved, and the planning and covering of the network are facilitated.

Description

technical field [0001] The invention relates to the field of communication, in particular to an antenna device with multiple boundaries and a reflector thereof Background technique [0002] In today's world, science and technology are changing with each passing day, and the development of the mobile communication industry is particularly rapid. As a result, higher and higher requirements are put forward for the indicators of base station antennas, especially in terms of bandwidth characteristics, cross-polarization characteristics, and the variation of main lobe beam width with frequency. Fluctuation and beam convergence characteristics, etc. There are various factors affecting these antenna indicators, and the structure of the antenna, especially the structure of the reflector is one of the key factors. [0003] In a cellular mobile communication system, the basic structure of a sector-covered base station antenna is usually composed of a linear radiation array and a refle...

AI Technical Summary

Problems solved by technology

[0004] As we all know, ordinary reflectors are generally rectangular flat plates with only one reflective surface and two sides. Antennas composed of reflectors with this structure have narrow bandwidths and sudden changes in the main lobe beam width, making the beam convergence poor. It is difficult to realize the ultra-wide frequency band or multi-frequency base station antenna whose electrical index requires the main lobe beam to converge. At present, there is an urgent need for a new reflector and antenna device to solve this technical problem.
