Description
Technical field
The present invention relates to Waveguide slot antenna technical fields, and the waveguide for being specially able to achieve one-dimensional wide-angel beam scanning is whole
Hold leaky antenna array.
Background technique
Waveguide slot antenna has the features such as compact-sized, power capacity is big, and aperture efficiency is high, and compare other antenna classes
Type has irreplaceable advantage in terms of satellite communication, aerospace.It is opened according to certain rules on wave guide wall it is elongated
Crack is activated gap by the current path on cutting wave guide wall, and the electromagnetic wave transmitted in waveguide is by gap to certainly
The aperture antenna formed by being radiated in space.
In order to improve the beam scanning range of antenna array, it is desirable to reduce the spacing between antenna element scans to eliminate wide-angle
When directional diagram graing lobe.
For traditional rectangular waveguide broadside leaky antenna, it is limited to the length of waveguide broadside, between two antenna slots
Distance often on the order of magnitude of 0.7 times of wavelength, excessive array element spacing will lead to antenna the wide-angle scanning the case where
Under there is graing lobe, in order to reduce array element spacing, in low-frequency range, often add the method for ridge to reduce waveguide broadside by waveguide
Size, so as to make antenna array reach smaller array element spacing.
Rectangular waveguide narrow side is cracked generally, and there are two types of modes, are out inclined slot, are separately out longitudinal slot, for Narrow Wall of Waveguide
While opening R-joining antenna array, since gap inclination can cause higher cross polarization level, usually to be fallen on front using gap
Set the corresponding braking measure such as method.And when antenna scan angle is larger, using its cross polarization of adjacent waveguide gap anastrophe
Valve still occurs in the real space, this just needs a variety of methods in conjunction with overcoming this disadvantage.When opening longitudinal slot, due to wave guide wall
The characteristic of electric current, array element spacing are fixed as a waveguide wavelength, when carrying out antenna array phasescan, due to array element spacing mistake
Greatly, it may appear that grating lobe problem.Cope with array element spacing it is excessive the problem of, can be by the way that a pair of of corner cut rectangular metal diaphragm be placed in
The both sides of inclined slot on the narrow wall, the design in Lai Shixian waveguide narrow side non-inclined gap, and realize the array element of 0.5 times of waveguide wavelength
Spacing, see document, [Wang Wei, Jin Jian, clock up time broadband diaphragm motivate waveguide narrow side non-inclined gap to specific mentality of designing
Array antenna [J] microwave journal, 2005,21 (05): 30-33+45].
Waveguide slot antenna processing there are many method, can using wire cutting or numerical control machine tool technique to antenna structure into
Row cutting, then whole welding is carried out to antenna with vacuum brazing or Pervasion Weld Technology.But because current machining accuracy is asked
Topic, the size of drill bit when it come to arrive the wave guide slot array antenna of high band generally in 0.5mm, have to the overall structure of antenna
Very high requirement.In addition, being limited to the width of waveguide narrow side for the antenna array that waveguide narrow side opens R-joining or transverse joint
Degree, radiating slot need to be connected across between waveguide narrow side and broadside, and this structure applies in general to the single-row antenna array of low frequency, such as wants
The extensive antenna array of high band is formed, is difficult to process it.And for using the antenna to crack in ridge waveguide broadside, in height
Frequency range, the ridge in waveguide can become very thin, there is extremely harsh requirement to the intensity of machining accuracy and material.
The feeding network of wave guide slot array antenna is often divided into parallelly feeding, series feed and series-parallel three kinds of feed.
Using parallelly feeding network, the electromagnetic wave under any frequency reaches the row that each aerial radiation stitches from antenna array feed port
Journey be it is the same, be conducive to the bandwidth for promoting entire antenna array, but cause simultaneously entire antenna array feeding network height become
The complexity of height, design is also further up.And then structure is simple for series feed network, under centre frequency, electromagnetic wave is from antenna
The stroke that battle array feed port reaches each aerial radiation seam is the waveguide wavelength (n is positive integer) for differing n times, is unfavorable for designing
At all channel antenna battle array.
