Abstract
The utility model relates to an antenna on ceiling, in particular to a wide-frequency antenna on ceiling with wide frequency band, a low standing wave and a beautiful appearance and suitability for indoor installation. The wide frequency ceiling mounted antenna of the utility model comprises a radiation body, a base plate and an antenna cover; the radiation body is integrated by connecting the top ball crown and the bottom reversed cone, the bottom of the radiation body is arranged on the center conductor on the coaxial connector. The antenna cover takes a ball shape which is arranged on the base plate. The wide frequency ceiling mount antenna has a whole frequency band reaching up from 800 to 4000 MHz and a standing wave lower than 1.5, realizing the wider frequency band, lower standing wave portion and smaller horizontal picture out of roundness. The utility model has the advantages of completely complying with the requirements of the indoor covering system, wireless local area network and fixed wireless access system and so on.
Description
Technical field
The utility model relates to a kind of ceiling mount antenna, the Wide-frequency antenna on ceiling of particularly a kind of broadband, low standing wave, aesthetic in appearance, suitable indoor installation.
Background technology
At present, indoor covering system and WLAN (wireless local area network) are the important component parts of Modern Mobile Communications Systems, and Wide-frequency antenna on ceiling wherein is indispensable device.As the bulb that illuminator is used, following intelligent ShangWu Building, exhibitions venue, even high-end residential building all will need the installing broad-band ceiling mount antenna.
In order to allow the ceiling mount antenna of indoor covering system realize that multiband is shared, need to solve the wideband problem of antenna, and the measure of prior art widening frequency band all is the shape and size that change antenna radiator, thereby realizes the purpose of widening frequency band.Existing antenna radiator has the employing truncated cone-shaped, also have and adopt single cone or large and small cone, but the communication band scope maximum that covers can only reach 800～2500MHz, and is discontinuous, only covers two frequency ranges of 806～960MHz and 1400～2500MHz.Even reach so wide frequency range, the maximum of another technical indicator---standing-wave ratio still can not reduce, and promptly standing-wave ratio can only be less than 1.8, especially at high frequency band as 2400～2500MHz, the antenna effect has reached the limit.In addition, the deviation in roundness of the existing horizontal radiation pattern of Wide-frequency antenna on ceiling in broadband is poor, high-end particularly serious at frequency band, thus influence the uniformity of indoor covering.
Summary of the invention
The purpose of this utility model provides the Wide-frequency antenna on ceiling of a kind of broadband, low standing wave, aesthetic in appearance, suitable indoor suction top installation.
Wide-frequency antenna on ceiling described in the utility model comprises radiant body, base plate, radome, and radiant body is connected as a single entity by the spherical crown on top and the inverted cone of bottom, and the bottom of radiant body is fixed on the center conductor of coaxial connector of base plate.
Wide-frequency antenna on ceiling described in the utility model equidistantly is connected to ground strip between radiant body outer surface and the base plate.
Wide-frequency antenna on ceiling described in the utility model, radome are spherical, are fixed on the base plate.Equidistantly be connected to pillar between radome inwall and the base plate.
The circular cone base angle of radiant body described in the utility model is 80～160 degree, and the total height of radiant body is 40～70mm.The width of ground strip is 1.5～8mm, and thickness is 0.2～3mm.The distance of the spherical crown of radome and radiant body is 0～6mm.
The frequency band of Wide-frequency antenna on ceiling described in the utility model reaches 800～4000MHz full frequency band, and standing-wave ratio is less than 1.5, has realized than wideer frequency band of similar ceiling mount antenna and lower standing-wave ratio.The frequency band of this Wide-frequency antenna on ceiling not only covered CDMA low band between 800～2400MHz (824～896MHz), global system for mobile communications GSM (870～960MHz), digital communication system DCS (1710～1880MHz), Personal Handyphone System Personal Handyphone System(PHS) PHS (1850～1990MHz), Universal Mobile Telecommunications System UMTS (1920～2170MHz), also extend to WLAN (wireless local area network) WLAN between 2400～4000MHz (2400～2500MHz), fixed wireless access system (3400～3600MHz).At wide frequency band range like this, the standing-wave ratio of this Wide-frequency antenna on ceiling still can meet the needs of indoor covering system, WLAN (wireless local area network) and fixed wireless access system etc. fully less than 1.5.
Wide-frequency antenna on ceiling described in the utility model has improved the structure of radiant body, has connected level and smooth metal sphere on the top of circular cone, makes the reflection coefficient of irradiator surface distributed current very little, thus effectively broadening the impedance bandwidth of antenna.The utility model has also adopted equally spaced ground strip, can improve the deviation in roundness of the horizontal radiation pattern of antenna more than 50%.Adopt the spherical antenna cover that matches with radiant body simultaneously, when making antenna shapes attractive in appearance, help further to reduce standing-wave ratio.
