Abstract
A swept type microstrip double polarization antenna unit is characterized in that swept type microstrip double polarization antenna unit is formed by the crossing of two microstrip symmetrical oscillators (1,2) with the same structure; the two sides of the microstrip symmetrical oscillators (1,2) are all provided with a swept type mantle (4) which is in an acute angle with a body (3) printed with the antenna; the lower side of the body(3) of the microstrip symmetrical oscillators (1,2) is arranged on a base and is connected with a corresponding feed network or a bottom board. The swept type microstrip double polarization antenna unit has the advantages of having a simple structure form and a simple feed form, greatly reducing the working procedures during the processing and mounting processes, improving the efficiency and being very applicable fro batch production.
Description
Technical field
The utility model relates to a kind of dual polarized antenna unit, specifically a kind of sweepback band dual polarized antenna unit that declines.
Background technology
Along with further developing of 3G technology, the demand of double polarization T D-SCDMA smart antenna is brought into schedule.The common bandwidth of dual polarized antenna unit at present commonly used is wide inadequately, and version and feed form more complicated all, and the installation and processing operation is loaded down with trivial details, is unfavorable for batch producing.
Summary of the invention
The purpose of this utility model is a kind of simple in structure, processing of design, it is simple to install, and under the prerequisite that satisfies existing 3G antenna performance index request, the band dual polarized antenna unit that declines of the sweepback with wideer bandwidth.
The technical solution of the utility model is:
A kind of sweepback band dual polarized antenna unit that declines, it is characterized in that it is intersected to form by two identical little band symmetrical dipoles 1,2 of structure, the both sides of little band symmetrical dipole 1,2 all have the swept-back spademan 4 that is acute angle with the main body 3 that is printed with antenna, and following being installed on the base and with corresponding feeding network or base plate of the main body 3 of described little band symmetrical dipole 1,2 links to each other.
The beneficial effects of the utility model:
1. the utility model adopts printed board processing to assemble, and version is simple, and the feed form is simple, has reduced operation greatly in processing, installation process, has improved efficient, is highly suitable for producing in batches.
2. the double-vane angle of two symmetrical dipoles of swept-back microstrip antenna can be regulated, and reaches the purpose that changes antenna element lobe width and lobe shape with this, is applicable to the different demands of different occasions.
3. the beamwidth of antenna has obtained very big improvement, except 1880MHz-1920MHz and two frequency ranges of 2010MHz-2025MHz commonly used, can also cover the 2300MHz-2400MHz frequency range.
Change the length of little band symmetrical dipole both wings simultaneously, also can change the frequency range of its use, need finely tune the width of microstrip line on the oscillator certainly simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of sweepback band dual polarized antenna unit that declines, it is intersected to form by two identical little band symmetrical dipoles 1,2 of structure, the both sides of little band symmetrical dipole 1,2 all have the swept-back spademan 4 that is acute angle with the main body 3 that is printed with antenna, and following being installed on the base and with corresponding feeding network or base plate of the main body 3 of described little band symmetrical dipole 1,2 links to each other.But described little band symmetrical dipole 1,2 square crossings also can non-perpendicularly intersect, and form a dual-polarized radiator between the two, can be connected with other parts by a base.Change the angle (being the sweepback angle) of the length of spademan 4 of two little band symmetrical dipoles 1,2 and glue itself and main body 3, can regulate utilized bandwidth and unit lobe width and shape.The adjusting of microstrip line can also change input impedance to be applicable to different feeder systems on little band symmetrical dipole.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
Claims (3)
1, a kind of sweepback band dual polarized antenna unit that declines, it is characterized in that it is by two little band symmetrical dipoles (1 that structure is identical, 2) intersect to form, little band symmetrical dipole (1,2) both sides all have the swept-back spademan (4) that is acute angle with the main body (3) that is printed with antenna, following being installed on the base and with corresponding feeding network or base plate of the main body (3) of described little band symmetrical dipole (1,2) links to each other.
2, the sweepback according to claim 1 band dual polarized antenna unit that declines is characterized in that the mode that described sweepback oscillator has a down dip.
