Embodiment

As shown in Figure 3, Figure 4, this is a kind of dual polarization antenna radiation unit to a preferred embodiment of the present utility model.This radiating element is combined into an entirety by four half-wave dipoles by base 5.Every two half-wave dipoles form the binary arrays of oblique 45 ° of polarization.Each half-wave dipole comprises support Ba Lun, radiation arm and feed structure.

In each half-wave dipole of this example, support Ba Lun and be made up of the support arm 3 that two have appropriate intervals, each support arm 3 supports a radiation arm 6.As can be seen from Figure 3, each radiation arm 6 is loaded on the upper end of support arm 3.Two radiation arms 6 extend suitable length in 90 ° of angles towards both direction; And between adjacent radiation arm, there is suitable gap.The end of each radiation arm 6 is also equipped with end connected vertically with it and loads 4.Four half-wave dipoles have eight radiation arms 6, and composition square structure (its length of side is 145.7cm) as shown in Figure 4, strictly speaking, this is a similar foursquare structure.During concrete enforcement, it also can be rectangular configuration.

In each half-wave dipole, feed structure comprises feed bridge 1 and cable (not shown).Feed bridge 1 is positioned at the top of support arm 3, and the top of one of them support arm 3 is provided with boss 2, and the top of another support arm 3 is provided with feed groove 8; One end of feed bridge 1 is welded on boss 2, and one end is connected with the inner core (not shown) of cable in addition.The outer conductor of cable is connected with the feed groove 8 on support arm 3 top.

As can be seen from Figure 3, often pair of oblique 45 ° of stretching, extensions downwards of support arm 3, its underpart is connected with base 5, forms the up big and down small structure shown in Fig. 3.Base 5 can be fixed in reflecting plate (not shown) by four screw holes again.

In this example, the upper surface of each radiation arm 6 is provided with two strip radiation arm grooves, 6, two radiation arm grooves 8 and sets gradually, in the present embodiment along radiation arm 6 direction of extension, two radiation arm grooves 8 are measure-alike, and with the center of radiation arm 6 for symmetrical structure.The width of radiation arm groove 8 is less than the width of radiation arm 6, and the degree of depth is less than the thickness of radiation arm 6, and the length sum of two radiation arm grooves is less than the length of radiation arm 6.During concrete enforcement, radiation arm groove can also be single or multiple, and size also can suitably adjust.After offering radiation arm groove, the weight of radiating element can be alleviated on the one hand; Be on the other hand under the prerequisite ensureing operational frequency bandwidth, make Signal transmissions more concentrated, thus improve gain, improve the property indices of radiating element.

If Fig. 5 is the schematic diagram using the existing radiating element composition multifrequency group battle array shown in Fig. 2; Fig. 6 is the schematic diagram using the composition of radiating element shown in Fig. 4 multifrequency group battle array.Contrast can be found out, when installing in identical installing space, the spacing between existing radiating element is 88.2cm, and the spacing in the present embodiment between radiating element is 134.3cm, greatly can increase spacing after visible its improves, thus the mutual coupling phenomenon between radiating element can be reduced.
