Abstract
The invention discloses a 3500MHz65-DEG duplex polarization platy antenna which is formed by distributing dipole radiation units on an underplate and connecting the distributing dipole radiation units through a feeder cable and a feeding network arranged at the back of the underplate; on the axes of the underplate along the length direction, a plurality of dipole radiation units are distributed on the surface of the underplate; each of the dipole radiation units comprises a pair of balanceable cross dipoles, a preset angle formed between the cross dipoles and the axes is +/-45 DEG, and the dipole radiation units are formed by the cross dipoles. By adopting a parasitic element, the invention ensures that a primary electric magnetic field induces current on the parasitic element, and the current emits secondary pole electric magnetic field which partially counteracts with the primary electric magnetic field so as to improve the isolation performance.
Description
Technical field
The present invention relates to a kind of antenna, particularly a kind of 3500MHz65 ° of double-polarization plate communication antenna.
Background technology
In the urban compact area,, adopt 65 ° of antennas in order to reduce interference to the adjacent area more.But because antenna insulate, the method for unique acquisition gain is that radiation is concentrated on some directions.Be subjected to condition effect such as service area shape, scope, channel quantity, thereby fail further to make the gain change of antenna big, enlarge the coverage rate of aerial signal from changing external condition.
Summary of the invention
The invention provides a kind ofly have that isolation performance is good, the standing wave performance is less than 1.5 3500MHz65 ° of double-polarization plate communication antenna.
In order to solve above technical problem, a kind of 3500MHz65 ° of double-polarization plate antenna of the present invention, by distribution dipole radiation unit on the base plate, the dipole radiation unit is formed by connecting by the feeding network at the feeder cable and the base plate back side, on along its length axis on the described base plate, a plurality of dipole radiation cell distribution are at backplate surface; Each dipole radiation unit of described a plurality of dipole radiations unit includes the cross-dipole of a pair of balance, and formed predetermined angular is ± 45 ° between described cross-dipole and the axis, forms the dipole radiation unit of dipole to forming that intersects.
Fixing feeder cable on the described dipole, the insulator of cable passes the end face of dipole, and inner wire is welded to connect with the film dancing that is welded on the dipole.
Described base plate upper edge axis direction vertically is equipped with several parasitic antennas.
The advantage of above structure is: adopt parasitic antenna to make primary magnetic field induce electric current on parasitic antenna, this electric current is launched time utmost point electromagnetic field and primary electromagnetic field partial offset again, to improve isolation performance.

Fig. 2 is the structural representation at the base plate of the present invention back side;
Fig. 3 is the structural representation of feeder cable of the present invention.
Embodiment
As shown in Figure 1, a kind of 3500MHz65 ° of double-polarization plate antenna of the present invention, some dipole radiations unit 2 distributes on the axis along its length of the front of described base plate 1, each dipole radiation unit 2 includes the cross-dipole 3 of a pair of balance, formed predetermined angular is ± 45 ° between described cross-dipole 3 and the axis, forms the dipole radiation unit 2 of dipole to forming that intersects.Just fix one on the base plate 1 between every two adjacent groups dipole radiation unit 2 along the vertical parasitic antenna 9 of axis direction.Dipole radiation unit 2 is by fixing feeder cable 4 on dipole 3.As Fig. 2, shown in Figure 3, the insulator 5 of feeder cable 4 passes the end face of dipole 3, and inner wire 6 is welded to connect with the film dancing 7 that is welded on the dipole 3.Feeder cable 4 is connected with the feeding network 8 at base plate 1 back side, forms double-polarization plate antenna.
