Abstract
The utility model discloses a wide frequency ceiling antenna which comprises a radiating body, a bottom plate and an antenna cover, wherein the upper part of the preference radiating body is of a ball table shape, the lower part of the preference radiating body is of an inverted cone shape, the preference of the radiating body is a metal radiating body, the bottom of the radiating body is tightly connected with an inner conductor of an antenna joint penetrating through the bottom plate, the antenna cover covers and contain the radiating body and is fixed on the bottom plate, the preference of the antenna cover 5 is a burnishing outer cover made from ABS materials, and in this way, the antenna is beautiful and durable and can be conveniently cleaned at the same time. Because the upper part of the radiating body of the utility model is of a ball table shape, the wide band frequency ceiling antenna of the utility model can spread the impedance bandwidth of the antenna by adjusting the height of the ball table and the radius of an upper circle and a lower circle of the ball table, can cause the impedance bandwidth of the antenna to be more spread by correspondingly adjusting the shape of the grounding pieces and the height and the width of a coupling adjusting piece and an adjusting ring for ensuring the wide frequency ceiling antenna have smaller full frequency band standing wave and better non-circularity.
Description
Technical field
The utility model relates to the mobile communication antenna field, relates in particular to a kind of Wide-frequency antenna on ceiling that is used for indoor covering system.
Background technology
Development along with the mobile communication cause, the network coverage is in continuous extension, for improving such as the market place builet below the ground, the station, the hotel, the communication quality of tunnel etc. service " blind area " adopts indoor distribution communication system usually, for realizing the shared bandwidth that just requires antenna to have broad of many networks, can realize that preferably the mobile communication full frequency band covers.How the purpose of existing widening frequency band is by changing the shape and size of antenna radiator, existing antenna radiator generally has several forms such as printed monopole, bicone, droplet-shaped monopole and distortion folded monopole (antenna), but the frequency range that covers generally all can only reach 800～2500MHz, and it is discontinuous, can only be in standing-wave ratio within the several frequency bands respectively less than 1.5, and have just taken standing-wave ratio into account and can't take the deviation in roundness of horizontal radiation pattern into account, thereby influenced the result of use of indoor distributed system.
The utility model content
Problem to be solved of the present utility model is to overcome the deficiencies in the prior art, provides a kind of and can guarantee at full range band 800～6000MHz standing internal wave than little, and have the Wide-frequency antenna on ceiling of horizontal radiation pattern deviation in roundness preferably.
For achieving the above object, the technical scheme that the utility model adopted is: Wide-frequency antenna on ceiling comprises radiant body, base plate, radome, the top of preferred radiant body is the billiard table shape, the bottom is inverted cone-shaped, the top of radiant body preferably is connected by welding manner with the bottom, radiant body is preferably the metal radiant body, the bottom of radiant body closely is connected with the inner wire of the antenna terminal that passes base plate, radome covers the containing radiant body and is fixed on the base plate, radome is preferably ABS material polishing outer cover, also makes the easy to clean of antenna like this when making antenna attractive and durable.
Also being connected between described radiant body outer surface and the base plate a plurality ofly has along the equally distributed ground strip of circumference, can change the electrical performance indexes of Wide-frequency antenna on ceiling by the shape that changes ground strip.
Described base plate is provided with a plurality of along the equally distributed coupling ground strip of circumference.
Accompany adjustable ring between described radiant body bottom and the base plate, highly can control standing wave by changing it.
Equidistantly be distributed with the support column of supporting antenna cover in the described radome, described support column is fixed on the base plate.
The frequency band of Wide-frequency antenna on ceiling described in the utility model reaches 800～6000MHz full frequency band, has realized the frequency band wideer than similar antenna, lower standing-wave ratio and better deviation in roundness.
The beneficial effects of the utility model are: Wide-frequency antenna on ceiling described in the utility model, because the top of its radiant body is the billiard table shape, height that can be by adjusting billiard table and billiard table be the impedance bandwidth of radius of a circle broadening antenna up and down, and the height and the width of shape, coupling adjustment sheet and adjustable ring that can be by corresponding adjusting ground strip make antenna impedance bandwidth broadening more, guarantee that Wide-frequency antenna on ceiling is less in 800～6000MHz full frequency band standing-wave ratio, and had deviation in roundness preferably.
