Abstract
The utility model discloses an ultra-thin wideband omni-directional ceiling antenna including an antenna cover and a radiator. The radiator includes a thin-plate-type radiator, a connection piece and a coaxial cable. The radiator is disposed in the antenna cover. The connection piece is disposed on the back of the thin-plate-type radiator. The thin-plate-type radiator is composed of a double-deck oxidation plate. The front face of the double-deck oxidation plate is coated with copper to form a micro-strip oscillator. The back face of the double-deck oxidation plate is coated with copper to form an antenna grounding sheet. The grounding sheet is in the bottom of the antenna cover. A hole is arranged in the double-deck oxidation plate. The coaxial cable goes through the hole and is welded on the double-deck oxidation plate. An inner and an outer conductor of the coaxial cable connect with the micro-strip oscillator and the grounding sheet in the radiator respectively. The ultra-thin wideband omni-directional ceiling antenna in the utility model has advantages of small thickness, small volume, low cost, simple assembly and the like.
Description
Technical field
The utility model relates to a kind of antenna, relate in particular to a kind of LTE of being used for, CDMA, GSM, DCS, PHS, 3G, WLAN, WIFI frequency range novel wideband, frivolous, make the all-around top absorbing antenna simple, that cost is low.
Background technology
Antenna is the indispensable critical piece of present social electronic applications, and the size of its volume and the height of cost directly have influence on the customers of installation environment and use.
Its radiant body of present ceiling mount antenna adopts ball oscillator or cylinder oscillator more; Its weak point is that cost is high, and the aerial radiation volume is bigger, in the ceiling mount antenna space of traditional structure; Volume is bigger; Cost is high, and production process complicacy etc. can not satisfy telecommunications company to product requirement cheaply on original basis.
The utility model content
The purpose of the utility model is exactly the deficiency for the ceiling mount antenna technology that solves traditional structure and space, and a kind of ultrathin ceiling mount antenna is provided.
The utility model adopts following technical solution to realize:
A kind of ultra-thin wideband omni-directional ceiling suction antenna comprises radome, radiant body, it is characterized in that, said radiant body comprises sheet-type radiant body, connector and coaxial cable, and radiant body is installed in radome inside, and connector is arranged on the back side of sheet-type radiant body; Said sheet-type radiant body is made up of a double-deck oxidation plate; Said double-deck oxidation plate front is covered copper and is formed micro-strip oscillator; Said double-deck oxidation plate reverse side covers copper and forms the antenna ground sheet, and said ground strip is then in the radome bottom; Have an aperture on the double-deck oxidation plate, said coaxial cable passes this aperture, is welded on the double-deck oxidation plate; The inner wire of said coaxial cable and outer conductor respectively with radiant body in micro-strip oscillator and ground strip be welded to connect.
As further specifying of such scheme, the dielectric constant of said double-deck oxidation plate is 4.4.
The internal clearance of said sheet-type radiant body and radome is 0.5mm.
The overall dimension of said antenna is 160mm*135mm*5mm.
The operating frequency of said antenna is 698-960/1710-2700MHz.
Through adopting the aforementioned techniques scheme, the beneficial effect of the utility model is: adopt radiant body to replace traditional ceiling mount antenna structure radiant body, many radiant bodies around having reduced have reduced cost on the one hand, can enhance productivity greatly; On the other hand, micro-strip oscillator directly covers copper on radiant body, and structure is more reliable, and performance is more stable; Use the ceiling mount antenna of this kind structure to have thin thickness, volume is little, and assembling is simple; Cost is low, advantages such as wideband, and the assembly process that has remedied the ceiling mount antenna traditional structure is complicated; The space is big, and the weak point that cost is high is applicable to the requirement that indoor omnidirectional covers.

Description of reference numerals: 1 radome, 2 sheet-type radiant bodies, 3 connectors, 4 coaxial cables.
Embodiment
With reference to figure 1, Fig. 2 and shown in Figure 3, the ultra-thin wideband omni-directional ceiling suction antenna of the utility model, it comprises radome 1, sheet-type radiant body 2, connector 3, coaxial cable 4.Said radiant body comprises sheet-type radiant body 2, connector 3 and coaxial cable 4, and radiant body is installed in radome inside, and connector 3 is arranged on the back side of sheet-type radiant body 2; Wherein, said connector 3 is made with copper product, is used for fixing the outer conductor of coaxial cable 4, fixes with the crimping mode, and the heart yearn of coaxial cable 4 need expose connector 3 terminal 3mm, and said coaxial cable 4 adopts commercially available SYV-50-3 cable, and length is 300mm.Connector 3 is fixed on sheet-type radiant body 2 reverse side with welding manner; Said sheet-type radiant body 2 is made up of a double-deck oxidation plate; Be of a size of the thick 1mm of the wide 131mm* of long 156mm*; Sheet-type radiant body 2 is opened the aperture place and is used for through firm welding behind the said coaxial cable core wire, the welding of the front of said coaxial cable core wire and sheet-type radiant body 2.Radome 1 inner button bit is used for fastening sheet-type radiant body 2; Said radome 1 adopts high-intensity plastic material moulding, and the front of sheet-type radiant body 2 is positioned at radome inside, and the reverse side of said sheet-type radiant body 2 is positioned at radome 1 bottom, and said sheet-type radiant body 2 is 0.5mm with the internal clearance of radome 1.This antenna shapes is of a size of 160mm*135mm*5mm, and operating frequency is 698-960/1710-2700MHz.Its standing-wave ratio of test shows is less than 2; Gain low frequency 2dBi; High frequency 4dBi satisfies the needs that the wide angle of indoor covering systems such as LTE, CDMA, GSM, DCS, PHS, 3G, WLAN covers fully, has realized the cost lower with similar wideband omni-directional ceiling suction antenna with small and exquisite volume.
Be merely one of the utility model embodiment shown in the utility model the foregoing description and the accompanying drawing, can not limit to the utility model with this.Under the condition that does not break away from the utility model marrow, any change that those skilled in the art did all belongs to the protection range of the utility model.
