Problems solved by technology

However, to achieve dual polarization under the premise of ensuring the performance of the ceiling antenna, the size of the antenna will generally become large, and it is easy to be rejected by users during use. Therefore, the development of a miniaturized dual-polarization ceiling antenna is of great significance

Abstract

The invention discloses a 4G indoor ceiling-mounted gain antenna. The 4G indoor ceiling-mounted gain antenna includes an antenna cover and a bottom plate. A biconical antenna and a microstrip round plate antenna are mounted in a space defined by the antenna cover and the bottom plate. The biconical antenna is composed of an upper cone and a lower cone. The upper cone and the lower cone are connected to each other through a connection nut and a plastic sleeve cap, so that vertical wave radiation is formed. The microstrip round plate antenna includes a two-layer PCB substrate made of F4B material. The PCB substrate is supported between the upper cone and the lower cone by a plurality of supporting rod. The front face of the PCB is provided with a plurality of hook-shaped copper-coated parts connected together and forming an enclosed area. The back face of the PCB is provided with a plurality of T-shaped copper-coated parts connected together and forming an enclosed area. Therefore, horizontal wave radiation is formed. By adopting the above design, standing-wave ratio of the antenna can be reduced, antenna performance can be improved effectively and antenna pattern non-roundness can be reduced.

Description

technical field [0001] The invention relates to the antenna field technology, in particular to a gain 4G indoor ceiling antenna. Background technique [0002] The indoor distribution system is an important part of today's wireless communication system, and the performance of the indoor distribution antenna directly affects the overall performance of the system. With the rapid development of mobile communication systems, the complexity of the system is getting higher and higher, which also puts forward new requirements and challenges for the performance of the antenna. Moreover, as users' awareness of protection against antenna radiation increases, stricter requirements are placed on the size of the indoor distribution system. Therefore, designing and adopting a new type of miniaturized and high-performance indoor distribution antenna is very important to the indoor distribution system. [0003] At present, the implementation forms of indoor ceiling antennas include single ...
