Abstract
The utility model relates to a double-ridge waveguide leaky antenna unit with a packaging structure. The double-ridge waveguide leaky antenna unit comprises a tubular double-ridge waveguide with the I-shaped caliber, wherein coupling slots are respectively distributed on the narrow surface on one side of the double-ridge waveguide, flanges are respectively arranged at two ends of the double-ridge waveguide, and an antenna cover is arranged on the narrow surface of the double-ridge waveguide provided with the coupling slots. Elongated sealing rib plates are respectively arranged at the ridge outside positions of the wide surfaces arranged on two sides of the double-ridge waveguide, and two ends of the sealing rib plates are respectively connected with the flanges arranged at the two ends of the double-ridge waveguide. Supporting plates are respectively fixedly arranged at the sealing rib plate positions on two sides of the double-ridge waveguide. The double-ridge waveguide leaky antenna unit is packaged by aid of the thin-wall antenna cover which is conformal with the waveguide and tightly attached to a waveguide radiated slot. The rigidity of the double-ridge waveguide leaky antenna unit is improved by additionally arranging the sealing rib plates. The supporting plates are arranged at the sealing rib plate positions on the two sides, antenna unit packaging and assembling requirements are both considered, and therefore integrated assembling integration design of the double-ridge waveguide leaky antenna unit is effectively achieved.

Background technology
In certain type research of radar process, the radar working frequency range is L-band, and antenna element has adopted the double ridged waveguide form, to reduce the waveguide bore.With respect to the dipole planar array antenna, double ridged waveguide crack planar array antenna has the advantages such as volume is little, lightweight, processing is simple, debugging work load is little, but there are many difficulties in encapsulation, the mounting design of double ridged waveguide leaky antenna unit.The nearly 6000mm of this antenna element length, bore are " I " molded dimension 100mm * 60mm, and wall thickness is 2 mm only, are processed with many coupling slots on the side leptoprosopy, and the rigidity of whole part is relatively poor; The cross section of the double ridged waveguide of tubing shape as shown in Figure 6.And as antenna element, its environment for use is outdoor, must take necessary version that antenna element is encapsulated rear installation, makes it become one and can guarantee antenna array size installation accuracy, again independent used antenna element.
Summary of the invention
In order to solve the existing relatively poor problem of overlength double ridged waveguide leaky antenna unit rigidity, the utility model provides a kind of double ridged waveguide leaky antenna unit with encapsulating structure.
A kind of double ridged waveguide leaky antenna unit with encapsulating structure comprises that the bore of tubing shape is the double ridged waveguide of " I " type, be laid with coupling slot on the one side leptoprosopy of double ridged waveguide, the two ends of double ridged waveguide are respectively equipped with ring flange, double ridged waveguide has a side leptoprosopy of coupling slot to be provided with radome, improvement is: the outside of wide two lateral ridges of double ridged waveguide is respectively equipped with the sealing gusset of strip, and described sealing gusset two ends are connecting respectively the ring flange at double ridged waveguide two ends; The sealing gusset place of double ridged waveguide both sides is fixed with respectively supporting plate.
Described supporting plate seals gusset successively by rivet.
There is fluid sealant at the gap location of described radome and supporting plate and other faying face places respectively full-filling.
Useful technique effect of the present utility model embodies in the following areas:
1. design optimization double ridged waveguide tubing external configuration
Design feature according to antenna element, require and be convenient to the needs of package design for the rigidity that strengthens antenna element, optimal design double ridged waveguide tubing configuration, increased two ridges outside two places sealing gusset of waveguide tubing, reserve step and take into account radome encapsulation and follow-up assembling, solve the integrated needs of antenna element encapsulation assembling, increased the rigidity of antenna element;
2. design left and right sides integral type supporting plate integrative packaging is installed
Thin-wall long and thin design feature according to antenna element, for follow-up encapsulation and installation requirements, and make whole antenna element become a rigid unitary, designed left and right sides integral type supporting plate, take into account antenna element encapsulation, assembling needs, efficiently solve the integrated assembling Integrated design of antenna element;
3. design is with the conformal thin-wall radome of locking mechanism
Because antenna element adopts the protection of thin-wall long and thin conformal antenna cover, reliable for guaranteeing the radome assembling, when the radome moulding, in conjunction with waveguide tubing profile, leave the structure of falling R in the radome both sides, make radome when assembling can self-locking, guarantee its fitting tight reliability;
4. left and right sides supporting plate and double ridged waveguide are joined and do the hole, gap and other faying face places at radome and supporting plate, the preferably polyurethane sealant sealing of full-filling glue-joint strength, use simultaneously rivet to be coated with the polyurethane sealant riveted joint, strengthen the sealing surface connection reliability, guaranteed the reliable waterproof sealing of antenna element and good rigidity.
