Abstract

The invention provides a ceiling-mounted antenna which comprises a PCB, a first radiation portion, a first signal transmission line, a first reflection portion and a second reflection portion. One end of the second reflection portion is fixedly connected with the first radiation portion, the other end of the second reflection portion is fixedly connected with the first reflection portion, the first reflection portion is fixedly installed on the PCB, and the first radiation portion is connected to the PCB through the first signal transmission line. According to the ceiling-mounted antenna, due to the structural design of the first radiation portion, the integral size is reduced, signal processing capacity of the ceiling-mounted antenna is improved, the signal use ratio of a signal source is improved through application of the reflection portions, and the ceiling-mounted antenna is simple in structure and convenient to install, and cannot influence indoor decoration.

Description

technical field [0001] The invention belongs to the field of communication equipment, and in particular relates to a ceiling-absorbing antenna. Background technique [0002] The indoor ceiling antenna is an antenna used for indoor signal coverage of wireless communication. It is generally installed on the ceiling to provide wireless signal coverage for an area with a radius of tens of meters centered on it. Outdoor signal coverage uses plate antennas with high power, strong signal, and long coverage; and indoor coverage, such as venues, hotels, office buildings, movie theaters, residential buildings, etc., needs to be covered by indoor distributed systems, so ceiling mounts are used. The antenna has a beautiful appearance and does not affect the interior decoration. [0003] The working frequency band of the traditional ceiling antenna is 800MHz-2500MHz, so according to the conventional antenna design principle, its height is about 80mm-100mm. In some indoor occasions, it ...
