Description
Technical field
The present invention relates to the antenna equipment technical field, more particularly relate to a kind of composite type minor diameter double frequency omnibearing antenna.
Background technology
In the communication system, the feeding classification between the omnidirectional antenna units that the outdoor cell signal covers has series feed and middle feedback at present, and feedback; Series feed shortcoming is that the beamwidth of antenna is narrow, and the angle of declination of antenna low-and high-frequency is inconsistent, and different angle of declination designs are more complicated, and the consistency of standing-wave ratio is bad, and it is lower to gain, and secondary lobe is bigger, and the deviation in roundness of level side figure influences coverage in each Frequency point difference.Conventional and to present shortcoming be that antenna volume is big, cable is many and cabling is complicated, and loss is big, has limited antenna and has not reached very high gain, and deviation in roundness is poor, produces complicatedly, and consistency is poor, the cost height.At present the omnidirectional antenna that uses the outdoor cell signal to cover all is a single-frequency, at single communication system network, different communication networks however with antenna and website is installed, cause the waste of resource.
Summary of the invention
Purpose of the present invention is exactly provide for the deficiency that solves prior art a kind of simple in structure, easily manufactured, the precision height, and cost is low, and is in light weight, high performance composite type minor diameter double frequency omnibearing antenna.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of composite type minor diameter double frequency omnibearing antenna, it is characterized in that, it comprises metal circular tube oscillator, printed board, little band omnidirectional's oscillator and plastic support post, and little band omnidirectional oscillator is positioned in the metal circular tube oscillator.
As further specifying of such scheme, described little band omnidirectional oscillator has two half-wave dipoles, and two half-wave dipoles comprise four oscillator arms, and four oscillator arms are the adjacent end ground connection that directly links to each other.
Described two parallel placements of half-wave dipole leave distance each other.
By a metal micro-strip ground connection, the metal micro-strip earth connection equates to the distance of two half-wave oscillators between described two half-wave dipoles.
Four arms of described two half-wave oscillators directly link to each other with the metal micro-strip earth connection at abutting end, and the inboard of oscillator arms and outer end and metal earth connection have certain distance.
One rectangular little band ground connection is arranged between the described two metal circular tube oscillators.
Described little band omnidirectional oscillator is that the microstrip transmission line by a side of printed board carries out direct feed, and distributing point has a plated-through hole that little band omnidirectional oscillator is linked to each other with microstrip transmission line.
The center-aligned of described metal circular tube oscillator and little band omnidirectional oscillator, metal circular tube oscillator inwall has distance to the outer arm of little band omnidirectional oscillator.
The feeding classification of described metal circular tube oscillator is and the feed that is coupled by the printed board oscillator.
Described metal oscillator supports by plastic column and is positioned in the printed board.
Between the described two metal circular tube oscillators is to connect with micro-strip coplanar waveguide.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
1, the present invention includes a metal tube and a novel micro-strip oscillator, micro-strip oscillator is positioned in the middle of the metal tube, connect with co-planar waveguide between Unit two, simplified processing technology, improved precision, greatly reduce production cost, antenna diameter is little, and convenient installation interference resistance is strong, simple in structure, cost, the communication network of two different frequencies can use advantages such as an antenna and installation website.
2, a unit of the present invention has a metal tube and two U-shaped micro-strip oscillators to form the double frequency omnibearing antenna, according to facts have proved, compared with prior art, the interval between two frequency ranges can be adjusted in the dual-band antenna adjustment outside metal circular tube of this principle and little band omnidirectional's oscillator length and gap etc., also can form a UWB (Ultra Wideband) Antenna unit, and the vertical beam angle of declination of working frequency range internal antenna changes little, deviation in roundness is little, the consistency height, gain is high, a plurality of unit of convenient design.
