Problems solved by technology

However, the widest working frequency band of the existing indoor dual-polarized antenna can cover 790-960 / 1710-2690MHz at the same time, and it still cannot support the 700MHz spectrum of LTE, so it is not fully compatible with various standards in the mobile communication network.

Abstract

The invention discloses a dual-broadband and dual-polarization omni-directional ceiling antenna which comprises a reflecting plate, a first flaky oscillator and a flaky sheet oscillator, wherein the first flaky oscillator comprises a first radiating plate and a first fixing seat for fixing the first radiating plate; the second flaky oscillator comprises a second radiating plate and a second fixing seat for fixing the second radiating plate; the first radiating plate and the second radiating plate are both obliquely arranged on the reflecting plate; the first radiating plate is perpendicular to the second radiating plate; and feeding points connected with feeding cables are respectively arranged at the bottom of the first radiating plate and the bottom of the second radiating plate. According to the dual-broadband and dual-polarization omni-directional ceiling antenna disclosed by the invention, the first flaky oscillator and the second flaky oscillator respectively receive signals by adopting the radiating plates. Compared with a traditional oscillator arm of an indoor dual-polarization antenna, the dual-broadband and dual-polarization omni-directional ceiling antenna has the characteristic that the radiating area is greatly increased. The first flaky oscillator and the second flaky oscillator in the dual-broadband and dual-polarization omni-directional ceiling antenna also respectively comprise a first coupling piece and a second coupling piece, which can be used for further broadening the bandwidth, so that the dual-broadband and dual-polarization omni-directional ceiling antenna can meet various systems in a mobile communication network.

Description

technical field [0001] The invention relates to the field of mobile communication antennas, in particular to a dual-broadband dual-polarization omnidirectional ceiling-mounted antenna suitable for transmission and coverage of wireless signals in an indoor cellular mobile communication system. Background technique [0002] With the increasing number of modern high-rise buildings and the increase of mobile communication terminal users, the requirements for signal coverage, traffic density and data flow of mobile communication systems are also getting higher and higher. Due to the limitation of the height of the existing mobile base station, the communication signal sent by the base station cannot completely cover every corner of the high-rise building. An existing method for improving the omni-directional coverage of signals inside a high-rise building is to install an indoor antenna distribution system in the high-rise building. The indoor antenna distribution system include...
