Abstract

The invention provides a low-profile indoor coverage enhanced single-polarization omnidirectional ceiling antenna. The antenna comprises a floor, a radiator and an annular radiation assembly. The floor is a revolving body using the central line thereof as an axis. The radiator is arranged on the floor and comprises two hollow cylinders and circular truncated cones which are connected in sequence and different in diameter. The diameters of the radiator are gradually reduced towards the floor, the central lines of the cylinders and circular truncated cones are superposed, step parts are respectively formed at the connection part of the two cylinders, the connection part of the cylinder and the circular truncated cone and the connection part of the two circular truncated cones due to the sudden change of diameters. The annular radiation assembly is arranged on the top part of the radiator, the maximum diameter of the annular radiation assembly is identical with the diameter of the cylinder on the top of the radiator so as to enable the maximum radiation direction in the antenna to be close to the horizontal direction, and the low elevation gain is increased. The central lines of the floor, the radiator and the annular radiation assembly are superposed. According to the invention, the low profile and the miniaturization of the antenna are realized, and the low elevation gain is increased.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a low-profile indoor coverage-enhanced single-polarization omnidirectional ceiling antenna. Background technique [0002] At present, mankind has entered the information age in an all-round way, and obtaining information has become an indispensable part of people's daily life. With its unique convenience, mobile communication has become the main way for people to obtain information and communicate with each other anytime and anywhere. The antenna is a key sub-component of the wireless communication system, and its performance has a decisive impact on the entire system. With the development of mobile communication technology, indoor environments such as homes, offices, shopping malls, terminal buildings, classrooms, libraries, etc. have become hot spots for traffic and data traffic. Due to consideration of coverage, site selection, cost and other practical factors, the outdoor macro base...
