Abstract

The invention provides a ceiling-mounted antenna, comprising a PCB board, a connecting part, a first radiating part, a second radiating part, a first signal transmission line, a second signal transmission line and a fixing part, and the two ends of the connecting part are respectively fixedly connected to the The PCB board and the second radiating part, the fixing part fixes the first radiating part to the second radiating part, the first radiating part and the second radiating part are electrically connected to the PCB board through the first signal transmission line and the second signal transmission line respectively. The ceiling antenna of the present invention reduces the overall volume through the design of two radiating parts, increases the working frequency band by using the two radiating parts at the same time, and expands the working frequency range of the ceiling antenna; The efficiency of the ceiling antenna. The ceiling-mounted antenna of the invention is simple in structure, convenient in installation, and does not affect 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 ...
