Description
Technical field
This invention is mainly used in the production design of antenna, relates in particular to and present array antenna and processing molding method thereof.
Background technology
The major defect of the continuous slit of the generalized waveguide that medium is filled joint array antenna is a dielectric loss, and dielectric loss is at the millimeter wave frequency band highly significant.Other shortcoming also comprises: because expensive with the fluctuation of environmental change and special microwave material of the unsteadiness of the inhomogeneities of medium and the material parameter that anisotropy causes, dielectric material parameter, or the like.
The structure that the microwave structure of fills with air and medium are filled is compared, and dielectric loss significantly diminishes, and has overcome the inhomogeneities of dielectric material itself and the unsteadiness of the material parameter that anisotropy causes.In addition, because electromagnetic energy is by air rather than medium media transmission, therefore, the continuous slit of generalized waveguide joint array antenna can select those that good physical characteristic is arranged but the very poor engineering plastics (as: ABS) of microwave property are made, and coating can be simulated metallic conductor well in the surperficial spray metal of these class engineering plastics.But the microwave structure of fills with air also has problems, particularly for waveguiding structure, because the microwave circuit characteristic needs the accuracy of waveguide inside dimension to guarantee, and the product of waveguiding structure assembling is the machining accuracy that can't detect its inside dimension by external instrument after finishing, this just requires us will propose the processing method of the continuous slit of a kind of generalized waveguide at fills with air joint array antenna, this method can each parts of strict guarantee accurate location and machining accuracy, can on wave guide wall, provide evenly continuous conduction slit with convenient welding simultaneously again.
This invention for and present the continuous slit of generalized waveguide joint array antenna two kinds of effective processing molding methods be provided, this method also is applicable to the machine-shaping of the continuous slit of series feed generalized waveguide joint array antenna.
Summary of the invention
The radiating element permutation and combination is saved in the continuous slit of several generalized waveguide, and forms and present the continuous slit of generalized waveguide joint array antenna by the feeding network feed arranged side by side that parallel-plate waveguide is formed.The continuous slit of processing and feedback generalized waveguide joint array antenna has two kinds of methods.First method adopt to stretch or the extrusion die moulding, and this method is applicable to that the waveguide medium is the situation of dielectric material, especially be fit to than low-frequency range and present the continuous slit of generalized waveguide joint array antenna; Second method, adopt the moulding process of hierarchy, this method is applicable to that mainly the waveguide medium is the situation of air, specifically comprises: at first and present the continuous slit of generalized waveguide joint array antenna and be divided into several layers, each layer utilizes traditional machine to add or the mould molding technology; Then, utilize ultrasonic bonding or Vacuum Soldering Technology, these metal materials or outer surface are done metalized plastic material the hierarchy assembling and weld together.
And present structure more than series feed complex structure, therefore processing molding method involved in the present invention is primarily aimed at and presents the continuous slit of generalized waveguide joint array antenna, but also is applicable to the machine-shaping of the continuous slit of series feed generalized waveguide joint array antenna.
For the waveguide medium is the situation of dielectric material, according to and present the cross-sectional structure precise design mould of the continuous slit of generalized waveguide joint array antenna, adopt stretching or extrusion process to produce the dielectric member part of the array antenna of different in width, do metallization process then handles on this dielectric member surface, grind away excitation port by grinding technics at last, radiation port and along the coat of metal on two end faces of array antenna Width, the medium that is in these positions partly is exposed in the air, and the metal of dielectric member both sides part has just constituted and has presented the parallel-plate waveguide feeding network and the continuous slit of the generalized waveguide joint radiating element of the continuous slit of generalized waveguide joint array antenna together with the filled media part like this.Adopt this technology, maximum benefit is: whole array does not need bonding or welding without any the splicing slit.But when the width of array antenna is remarkable, guarantee that whole array structure is reliable, transformer section in the feeding network and T type branch just can not be too thin, and therefore, this method relatively is fit to apply to than processing and manufacturing low-frequency range and that present the continuous slit of generalized waveguide joint array antenna.
For the waveguide medium is the situation of air, adopts hierarchical process, promptly whole and the continuous slit of feedback generalized waveguide joint array antenna is done longitudinally cutting, and from top to bottom, subdivision is a several layers successively, and each layer utilizes traditional machine to add or the mould molding technology; Then, utilize ultrasonic bonding or Vacuum Soldering Technology, these metal materials or outer surface are done metalized plastic material the hierarchy assembling and weld together.Use these ripe technical processs, can guarantee that product has lower or medium processing cost, is beneficial to the production in enormous quantities in the industrialization process.
The structure that the microwave device of cavity (that is: air transfer medium) structure and medium are filled is compared, and dielectric loss significantly diminishes, and has overcome the inhomogeneities of dielectric material itself and the unsteadiness of the material parameter that anisotropy causes; In addition, at the metal and the air interface place of cavity structure, metal wall surfaces is very smooth, and at the metal and the dielectric interface place of medium interstitital texture, metal wall surfaces is more rough, therefore, the former conductor losses is far smaller than the latter's conductor losses, especially at millimeter wave frequency band.
Because electromagnetic energy is by air rather than medium media transmission, therefore based on the consideration of product cost aspect, the continuous slit of generalized waveguide joint array antenna can select those that good physical characteristic is arranged but the very poor engineering plastics (as: ABS) of microwave property are made.Utilize traditional machine to add or injection mold produces each laminated plastics member, use metallization process (vacuum deposition+electroless plating) or laminating technology then, spray or laminate metal level in order to the simulation metallic conductor on the surface of these laminated plastics members, this processing molding method is fit to the production in enormous quantities of low-cost antenna very much.
Need close tolerance to cooperate and application scenario firm in structure for those, the laminated element of whole array antenna just can not be selected plastics, and must select metal material (for reducing weight, generally selecting aluminium).For reducing conductor losses, these layered metal members need be done surface treatment, utilize specific frock clamp and Vacuum Soldering Technology that their are assembled and be welded into an integral body at last.
The feeding network that utilizes parallel-plate waveguide to form carries out (parallel connection) feed side by side to the radiating curtain that is arranged in a combination by the continuous slit of generalized waveguide joint radiating element, form and the continuous slit of feedback generalized waveguide joint array antenna, the array antenna of this structure has ultra broadband and high-efficiency characteristics, be highly suitable for multi-functional military channels or commercial signal communication system (digital microwave and global satellite communication), above-mentioned hierarchical process is of value to machine-shaping this and the continuous slit of feedback generalized waveguide joint array antenna.
