Specific implementation mode：
The utility model is further illustrated with reference to specific embodiments and the drawings.
As Figure 1-Figure 2, a kind of low frequency integrated radiation unit described in the utility model, the radiating element include one
A annular base 1 shakes in the periphery of annular base 1 in four orientation of " ten " font distribution, obliquely to forming four groups
Sub- arm 2, every group of oscillator arms 2 include two spaced and parallel arrangements being connect with annular base 1 arc oscillator arms 21 and respectively at
Type arc oscillator arms 21 upper terminal part and respectively in the arc oscillator arms 21 towards both sides adjacent sets end bending extend it is straight
Shape oscillator arms 22；It is connected with feed tab 3 between the end of two arc oscillator arms 21 of every group of oscillator arms 2；The straight of adjacent sets
There is spacing between the terminal part of oscillator arms 22 and the first oscillator buckle 4 is installed；It is in inverted " u "-shaped that first oscillator, which buckles 4 both ends,
Buckle 41, is connected to the end of two straight oscillator arms 22 of two adjacent groups oscillator arms 2, and centre is isolation part 42, isolation part 42
The distance between thickness and two 22 terminal parts of straight oscillator arms are suitable.
First oscillator buckle 4 is made of dielectric plastic material, and good fixation can be played by the first oscillator buckle 4
The intensity for acting on and reinforcing oscillator arms 2 makes to keep between oscillator arms 2 spacing and more stable, will not be due to by external force factor
Phenomena such as generating oscillator arms deformation, to ensure that the electric property of product is stablized.
Further, the second oscillator buckle 5, the second oscillator clamp are installed between the arc oscillator arms 21 of every group of oscillator arms 2
Button 5 is in " E " font, while withholding two arc oscillator arms 21 in one group of oscillator arms 2 and midfeather gap and " E " word
The thickness at the intermediate position of shape buckle is suitable, keeps the two spacing to stablize indeformable；Second oscillator buckle 5 can not only play further
The effect of fixed oscillator arms 2, while can also play the role of fixed cable 6, so that cable 6 is fixed with oscillator arms 2, keeps cable
6 is firm with the welding position of feed tab 3；
In conjunction with shown in Fig. 3, Fig. 4, Fig. 5, an arc oscillator arms end in two arc oscillator arms 21 of every group of oscillator arms 2
A through-hole 211 is offered at end, the longitudinal edge periphery of the feed tab 3 is arranged there are two round locating ring 31 and leads to mounted on this
In hole 211；Another arc raises one's arm end equipped with raised feeder pillar 212, and the lateral edge tail of feed tab 3 is welded on the feedback
On electric column 212.Feed tab 3 is designed in inverted "L" shape, and feed tab 3 is installed by two round locating rings 31, not only easy for installation
Fast, it also ensures that feed tab 3 is placed in the middle, convenient for being welded with the cable 6 of lower section, is also conducive to impedance matching, promotes standing wave performance；Together
When be also conducive to the replacement of feed tab 3, convenient for follow-up debugging.
In four the first oscillators buckle 4, two of which relative to the first oscillator buckle upper and lower surface respectively at

The lateral bending folding part 45 of two downside direction bendings outwardly；I.e. four the first oscillator buckles 4 are in asymmetric structure, thus it is possible to vary frequency
Straight oscillator arms 22 form an inside bending part 23, the bending with terminal part joining place in arc oscillator arms 21
Portion 23 can make the positions of straight oscillator arms 22 recess distance inwardly, be conducive to reduce Outside Dimensions, reduce occupied space,
Conducive to a group battle array.
In conclusion the utility model low frequency integrated radiation unit can keep adjacent vibration generators arm by increasing oscillator buckle
Between structural stability, avoid oscillator arms from being deformed because of external force, ensure the electric property of product；And feed tab only both ends are welded
It connects, main body is installed with oscillator arms by round locating ring, is replaced convenient for removing, convenient follow-up debugging；In addition, oscillator buckle uses
