Abstract
The invention discloses the preparation processes of phased array antenna gap waveguide layer, the structure of gap waveguide layer is split as entity between outer rim and gap in the design phase, reach reduction difficulty of processing, improve machining accuracy, ensure the purpose of yields, it is processed between outer rim and gap after entity by most practical technique, then entity between outer rim and gap is assembled, welding or bonding can be used in a combination thereof mode.
Description
Technical field
The present invention relates to especially phased array antenna gap waveguide layer preparation processes.
Background technique
It is more and more in high frequency antenna to use phased array antenna with the development of radar and communication technology of satellite, in phase
Gap waveguide layer is often used in control array antenna (such as CTS antenna, VCTS antenna) structure.Currently, gap in the prior art
The common preparation process of ducting layer is added using monolith machine, and this preparation process is in the presence of structure is complicated, processing difficulties, cost
High, the disadvantages of overall weight is big.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide phased array antenna gap waveguide layer preparation processes.
The purpose of the present invention is achieved through the following technical solutions: a kind of phased array antenna gap waveguide layer preparation process,
The gap waveguide layer is formed by outer rim and as entity between multiple gaps in outer rim, comprising the following steps:
S1. gap waveguide layer is split to design, i.e., the gap waveguide layer is split as entity two between outer rim and gap
Part；
S2. because between gap solid cross-section it is identical, therefore processed by the way of extrudate, and outer rim then using mechanical plus
Either type is processed in work, die casting or injection molding；
S3. solid profile and outer rim between the gap processed are combined into one.
Further, solid profile and the outer rim are connected by bonding way between the gap.
Further, solid profile and the outer rim are connected by welding manner between the gap.
Further, entity is hollow structure between the gap.
The invention has the following advantages that
1. simplifying structure, by complicated structurally reasonable fractionation, each section is made to become simple structure；
2. simplifying processing, outer rim installation positioning position precision is high after fractionation, and the processing is simple using extrudate for entity between gap；
3. reducing processing cost, entity is processed in a manner of profile between gap, and processing charges can be greatly reduced；
4. mitigating weight, entity is processed in a manner of profile between gap, can be made into hollow structure, overall weight can be effectively reduced.

Specific embodiment
To keep the purposes, technical schemes and advantages of inventive embodiments clearer, below in conjunction in the embodiment of the present invention
Attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is this
Invention a part of the embodiment, instead of all the embodiments.The present invention for usually describing and indicating in attached drawing here is implemented
The component of example can be arranged and be designed with a variety of different configurations.Based on the embodiments of the present invention, ordinary skill
Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
The present embodiment provides phased array antenna gap waveguide layer preparation processes.
Gap waveguide layer is as shown in Figure 1 and Figure 2, has outer rim 1, entity 3 and is made of entity between gap between gap
Gap waveguide 2, first in the design phase, to gap ducting layer carry out it is reasonable split design, gap waveguide layer is split as
Entity 3 between outer rim 1 and gap, such as the front elevation that Fig. 3 is outer rim 1 and the side view that Fig. 4 is outer rim 1, for another example Fig. 5 is
The side view of the front elevation of entity 3 and Fig. 6 entity 3 between single gap between single gap, by complicated structurally reasonable fractionation,
Each section is set to become simple structure, to achieve the purpose that simplified structure.
Suitable technique is selected to process entity 3 between the outer rim 1 and gap for splitting design, according to outer rim 1
Architectural characteristic may be selected add using machine, processed by the way of die casting or injection molding, and entity 3 then more uses shape extrusion between gap
Mode it is processed；After fractionation sub-unit processing avoid overall processing structure is complicated, processing difficulties, it is at high cost and
The big disadvantage of overall weight is realized and simplifies processing, and the precision at the installation positioning of outer rim 1 position is improved, and entity 3 passes through type between gap
Material processing, is made into hollow structure, processing charges can be greatly reduced and overall weight is effectively reduced, facilitate installation personnel
Installation operation in high altitude operation.
Entity 3 is assembled further according to the product parameters of phased array antenna between the outer rim 1 processed and gap, outside
Entity 3 can be used the mode being bonded or welded and be combined into one between frame 1 and gap.
The phased array antenna gap waveguide layer manufactured by the technique has the following advantages:
Splitting gap waveguide layer structure is that processing greatly simplifies, and the simplification of processing is torn open simultaneously so that the expense of processing is greatly reduced
Separation structure is processed so that the mode that shape extrusion can be used in entity 3 between gap is processed, by physical treatment between gap at
Hollow structure, significantly mitigation weight of equipment.
