Embodiment approach

[0029] In order to reduce the energy loss of the antenna unit and improve the radiation efficiency of the elliptical metal conductor 12, a low-dielectric constant and low-loss dielectric substrate is used. The antenna dielectric substrate is required to work at a frequency of 1GHz, with a nominal dielectric constant of ≤4.0 and a dielectric constant of ≤0.008. Electrical loss tangent. The thickness of the dielectric substrate 10 can range from 0.4 mm to 2 mm. The dielectric substrate 10 includes glass fiber cloth, epoxy resin and a compound that reacts cross-linked with the epoxy resin. The first type of implementation of the dielectric substrate is as follows:

[0030] The manufacturing process of the dielectric substrate is as follows: first, a wetting solution is provided including: a first component, which contains epoxy resin; a second component, which contains a compound that cross-links with the epoxy resin; and one or Various solvents. Wherein the first component an...

Abstract

Provided is a wireless fidelity (Wi-Fi) ceiling mounted antenna device. The Wi-Fi ceiling mounted antenna device comprises a reflecting piece and a radiating element fixed on the reflecting piece, wherein the radiating element comprises a dielectric substrate and a round metal conductor, and the round metal conductor is arranged on any one of two surfaces of the dielectric substrate. Radiation oscillator of a Wi-Fi ceiling mounted antenna is open, and the Wi-Fi ceiling mounted antenna is an oval or round monopole printed antenna, and the Wi-Fi ceiling mounted antenna device is simple in structure, good in performance index, and wide in application range due to the fact that a broadband design is adopted, and provides a workable frequency range for system upgrade.

Description

technical field [0001] The present invention relates to a ceiling antenna, and more specifically relates to a Wi-Fi ceiling antenna device. Background technique [0002] At present, as the layout of Wi-Fi hotspots becomes more and more dense, the demand for Wi-Fi antenna devices is increasing, and the number of Wi-Fi antenna devices deployed in a certain range is reduced. Therefore, for the antenna design industry, various factors such as the size, size, length, resonant frequency band, resonant bandwidth, applicable equipment environment, gain benefit, and field characteristics of the antenna restrict the development and design of the antenna. Especially the radiation pattern of the antenna and the high gain performance required by the antenna are a pair of prominent contradictions. [0003] At the same time, the Wi-Fi hotspot layout is invisible, and the size of the antenna needs to be solved. The existing Wi-Fi antenna can only cover the 2.4GHz working frequency band, ha...
