Abstract
The invention provides a method for protecting a signal transmission surface of an inner cavity of an antenna feeder. According to the method, the corrosion resistance and the long-term working reliability of a flat plate leaky antenna, a feed source and a wave guide can be significantly improved. The method is implemented through the following technical scheme: a) protecting electric contact parts of the flat plate leaky antenna, the feed source and the wave guide to be protected by using a pressure-sensitive tape or a strippable adhesive; b) treating silver-plated or gold-plated layer parts of signal transmission surfaces of feeder lines such as the feed source and the wave guide to be protected by using a silane coupling agent; and c) putting the flat plate leaky antenna, the feed source and the wave guide to be protected into a parylene-coated device, coating a membranous layer by using parylene through vacuum vapor deposition, and after coating, removing the protection of the pressure-sensitive tape and the strippable adhesive. According to the method, a parylene coating technique is used for protecting the signal transmission surface of the antenna feeder which cannot be protected by using the conventional method to solve the problem of performance reduction of the inner surface of the antenna feeder because of the corrosion caused by a protection dead corner.
Description
Technical field
The invention relates to antenna feeder device means of defences such as Planar Slot Antenna, feed, waveguide.
Background technology
The structural distinguishing feature of Planar Slot Antenna is multilayer, cavity and thin-walled, compact conformation complexity, required precision height.The general Planar Slot Antenna that adopts aluminum alloy materials high-speed cutting machine-shaping is a kind of with alignment pin and the clamping of frock assembling and positioning, the cavity type parts that vacuum brazing integral weld forming wall thickness is thin.Therefore after machining, the most basic chemical oxidation treatment all can not be carried out, and also can't carry out traditional protective treatment, can only rely on the corrosion resistance of material self to ensure the protective capacities of antenna,
In the conventional method of the present antenna feeder device protective treatment flow process that Fig. 3 shows, after the antenna feeder device fabrication was finished, Planar Slot Antenna can't be carried out protective treatment, directly handed over the tester to test after the assay was approved; After feed, waveguide machine, carry out gold-plated or silver-plated processing, part aluminium alloy feed, waveguide are carried out electric conductive oxidation and are handled, and finish dealing with and hand over the tester to test after the assay was approved.But conventional method can't be carried out the protective treatment of special-shaped feeder line.
Waveguide is a kind ofly to be used for retraining or the structure of guide electromagnetic waves.The advantage of waveguide is that conductor losses and dielectric loss are little; Power capacity is big; There is not radiation loss; Simple in structure, be easy to make.At millimeter wave and submillimeter wave wave band, the size of metallic waveguide can be very little, causes making and the plating difficulty.
The conductance of feed, waveguide tube wall is very high, generally makes with metals such as copper, aluminium.In order to reduce loss, usually silver-plated or gold-plated to the implementation of microwave components such as waveguide, but the protection question of its inner surface is outstanding, and easy to change, the blackout of silver coating commonly used has reduced signal transmission quality, has a strong impact on the complete machine performance.The feeder line that some complex structure and cavity size are too little, the shielding action of tube wall during owing to plating, a lot of zones of its inside cavity do not have coating, and rotproofness is very low, and matrix does not have the coating protection, influences its useful life greatly.
Recently, along with the popularization of lightweight requirements, materials such as aluminium alloy are used for the manufacturing of antenna, feeder line in a large number.Because the existence of aluminium alloy self corrosion stability difference and galvanic corrosion, the protection question of aluminium alloy antenna feeder device is more outstanding.
Summary of the invention:
The objective of the invention is protection deficiency at present Planar Slot Antenna, feed and waveguide, a kind of method that can transmit the face protective treatment to the inner chamber signal that can't carry out the tradition protection has been proposed, with the resistance to corrosion of raising Planar Slot Antenna, feed and waveguide and the reliability of long-term work.
In order to realize above-mentioned purpose of the present invention, the method for a kind of antenna feeder device inner chamber signal transmission face provided by the invention protective treatment is characterized in that comprising the following steps:
A) to the end face of flange position of Planar Slot Antenna, feed and the waveguide of wanting protective treatment, with pressure sensitive adhesive tape or peelable glue protection;
B) the facial position of the signal of feeder lines such as the Planar Slot Antenna that needs are protected, feed, waveguide transmission is carried out silane coupler and is handled;
C) will the protective treatment Planar Slot Antenna, feed and waveguide put into to send and draw the synthetic fibre coating equipment, carries out vacuum vapor deposition group and draw the synthetic fibre rete to handle, apply finish after, remove protection pressure sensitive adhesive tape or peelable glue.。
The present invention has following beneficial effect than prior art:
The present invention draws synthetic fibre to Planar Slot Antenna, feed and waveguide means of defence by vacuum vapor deposition group, can carry out protective treatment to the Planar Slot Antenna of not carrying out protective treatment at present, improve the resistance to corrosion and the environmental suitability of Planar Slot Antenna greatly; By the protective treatment that the silver-plated or Gold plated Layer of the signal of feeder lines such as feed, waveguide transmission face is carried out, can prevent silver coating variable color, blackout and corrosion, guaranteed signal transmission quality, realized that the sky watches the reliability of feedback system long-term work, resistance to corrosion and the environmental suitability and the useful life of having improved feeder line greatly.
The present invention utilizes to send and draws the synthetic fibre paint-on technique that the signal transmission face of the antenna feeder device that can't adopt conventional method protection is protected, the basic no change of electrical performance indexes before and after handling has been avoided antenna feeder device inner surface to cause corrosion because of the protection dead angle and has been caused the problem of decreased performance.
A key factor that influences aluminium alloy antenna feeder device Alloy instead of Copper alloy antenna feeder device is exactly a protection question, the present invention draws the synthetic fibre paint-on technique to solve aluminium alloy antenna feeder device protection question by group, for its Alloy instead of Copper alloy antenna feeder device has been cleared away obstacle, and then be that the weight that has alleviated the radar complete machine contributes.
The protection processing method of synthetic fibre rete draws in the vacuum vapor deposition group that the present invention taked, easy, protection cost in enormous quantities is low, both improved the resistance to corrosion of antenna feeder device matrix, guaranteed that again the antenna feeder working performance of devices is stable, prolong working life, simultaneously fundamentally solved the protective treatment problem that conventional method can't be carried out special-shaped feeder line.
The process for protecting method that the present invention taked requires not quite can put into vacuum moulding machine chamber antenna feeder device and all can carry out protective treatment to the version of antenna feeder device, and particularly little at physical dimension, the millimeter wave antenna feeder device that precision is high is particularly suitable.
