Abstract
The utility model relates to a low-profile double-frequency ultra-wideband antenna. The low-profile double-frequency ultra-wideband antenna is characterized by comprising a metal reflecting plate, a combiner and three radiators. The first radiator is an E-shaped metal sheet, is positioned above the metal reflecting plate, and is supported by a nonmetal member. Feed is carried out by the first radiator via a metal probe which is connected with the first input port of the combiner via a cable. The second radiator is a square sheet metal with branches and is positioned on one side of the first radiator. The center of the lower surface of the second radiator is connected with a meandering sheet metal for feed, and the meandering sheet metal is connected with the second input port of the combiner. The third radiator is a square sheet metal and is positioned right over the second radiator. The radiating area of the third radiator is smaller than that of the second radiator. The output port of the combiner is connected with a radio frequency connector via a cable. The beneficial effects of the utility model are that the low-profile double-frequency ultra-wideband antenna is low in profile height, small in size, can be hidden inside an indoor wall painting to serve as a mobile communication base station antenna.
Description
Technical field
The utility model relates to a kind of antenna, relates in particular to a kind of low section double frequency UWB Antenna.
Background technology
The 3G mobile communication technology requires the very high antenna of installation capability, at present, is installed on the signal that indoor antenna only can be received and dispatched the 2.5G network, can't satisfy the requirement of 3G; In addition,,, can not be integrated in the indoor ornament commonly used, can't satisfy indoor aesthetic property, concealed demand because volume is too big though some antenna can be received and dispatched the 3G signal.
Summary of the invention
It is little that the technical problem that the utility model will solve provides a kind of volume, can be hidden in the low section double frequency UWB Antenna in the indoor mural painting.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of low section double frequency UWB Antenna, it is characterized in that comprising metallic reflection plate, mixer and three radiant bodies, and first radiant body is an E shape sheet metal; It is positioned at metallic reflection plate top; Supported by non-metallic member, first radiant body is through the metal probe feed, and this metal probe connects mixer first input end mouth through cable; Second radiant body is the square metal sheet of band minor matters, and second radiant body is positioned at first radiant body, one side, and the second radiant body lower surface center is connected with sheet metal and carries out feed, and this sheet metal connects mixer second input port; The 3rd radiant body is the square-shaped metal sheet, and the 3rd radiant body is positioned at directly over second radiant body, and its swept area is less than second radiant body; The output port of mixer connects radio frequency connector through cable.
Further, the central axes of second radiant body and the 3rd radiant body.
Spacing between first radiant body and the metallic reflection plate is 10mm-30mm, and the spacing between second radiant body and the metallic reflection plate is 5mm-15mm, and the spacing between the 3rd radiant body and second radiant body is 5mm-15mm.
Through the spacing of controlling first radiant body and metallic reflection plate is 10mm-30mm; The spacing of second radiant body and metallic reflection plate is 5mm-15mm; The spacing of the 3rd radiant body and second radiant body is 5mm-15mm, makes that the section height of entire antenna is lower, possesses low section characteristic.First radiant body can be received and dispatched 824MHz～960MHz frequency signal; The 3rd radiant body and second radiant body can be received and dispatched 1710MHz～2500MHz frequency signal, and the interior standing-wave ratio of standing wave and 1710MHz～2500MHz frequency band in 824MHz～960MHz frequency band is less than 1.5.The utility model can be installed in the mural painting with the element antenna of two secondary microstrip antennas as two frequency ranges of antenna for base station, plays stealthy effect, reaches the harmony with environment; The utility model adopts two width of cloth microstrip antennas, has bigger gain and orientation direction preferably, has communication efficiency preferably.
Mixer possesses two input ports and an output port, and wherein the first input end mouth connects first radiant body transmitting-receiving 824MHz～960MHz frequency band signals, and second input port connects second radiant body transmitting-receiving 1710MHz～2500MHz frequency band signals; Mixer makes up 824MHz～960MHz frequency band signals, 1710MHz～2500MHz frequency band signals, with output port output, can cover 3G mobile communication frequency range then.
The metallic reflection plate is positioned at lowermost end, and in fact through components and parts such as fixing first radiant body of non-metallic member, second radiant body, mixers, the metallic reflection plate also is connected with the metal bottom surface of the outer layer metal screen of stube cable, mixer and carries out commonly.
In sum, the utlity model has that section height is low, volume is little, can be hidden in the beneficial effect that is used as antenna of mobile communication base station in the indoor mural painting.
