Description
Technical field
The present invention relates to based on the inflation ring structure ground with antenna reflector and application thereof, belong to communication technical field.
Background technology
Therefore reflector antenna has obtained using widely owing to can obtain higher gain.But the gain that reflector antenna can obtain is directly proportional with area, therefore under the occasion of pursuing high-gain, often needs bigger antenna diameter.At present, traditional reflecting surface is used the main solid face manufacturing technology that adopts, and promptly adopts mode integral body such as mould to process the reflecting surface of parabolic form; Because the reflecting surface volume of solid face manufacturing technology moulding is big; Be not easy to carry, therefore, use and mainly concentrate on fixed charge method earth station and automotive field.
In recent years, fields such as ground mobile forces, scientific investigation exploration, outdoor exercises have proposed the demand to portable reflector antenna.
The GATR company of the U.S. has proposed a kind of portable antenna based on spherical inflatable structure, and is as shown in Figure 1.
Be with five parts to form by inflation spherical frame, reflecting surface, feed, mounting base, sensing adjustment; Agent structure is a spherical gas cell body structure; Circular flexible paraboloid structure of inner installation is installed feed at parabolic gyroaxis of circle and the crossing position of spherical.Through the sensing adjustment band between adjustment mounting base and the inflation spherical frame, can adjust the sensing of reflecting surface.This antenna can be positioned in the less packing case through folding when packing, when needs work, forms structure as shown in Figure 1 through inflation.
People such as the Zhou Yijun of Zhejiang University, Guan Fuling have declared spherical ground-based surface antenna patent (patent No. CN102110867A), have inherited the scheme of U.S. GATR company basically, and unique difference is that feed is positioned over outside the spherical balloon separately.
Above-mentioned two kinds of antennas all are based on the ground of inflation technology and use antenna, are easy to carry, light weight.But the overall structure volume is big, windage is bigger.
Summary of the invention
The objective of the invention is in order to propose ground based on the inflation ring structure with antenna reflector and application thereof, this antenna is easy to carry, light weight, volume are little, and windage is little.
The objective of the invention is to realize through following technical scheme.
Antenna reflector is used on ground based on the inflation ring structure of the present invention, and this reflector comprises inflation ring and flexible paraboloid structure; Flexible paraboloid structure is made up of laterally zygomorphic two films, promptly goes up film and following film, forms cavity between two films; The periphery of last film and following film is fixed with the seamless bonding of interior side external surface of inflation ring; The outer surface of last film carries out metalized;
Above-mentioned flexible paraboloid structure adopts rubber or polyester material; Polyester material is Mylar or Kapton;
Above-mentioned method of carrying out metalized is in the outer surface copper facing of last film or aluminizes.
Of the present invention based on the application of the ground of inflating ring structure with antenna reflector: the air that will go up in film and the following film formed cavity is transferred, two parabolas of last film and the automatic formation of following film; The inflation ring is inflated, with the feed support bar feed is connected with the inflation ring then; And will inflate ring and support on the ground with pointing to the adjustment telescoping tube;
Totally three of feed support bars, along circumferentially evenly distributing of inflation ring, its length is confirmed according to the Antenna Design result; Point to the sensing that the adjustment telescoping tube is used to adjust flexible paraboloid structure; The version of pointing to the adjustment telescoping tube is the same with camera bracing frame or theodolite bracing frame, can realize the stepless adjustment of length direction, points to totally three of adjustment telescoping tubes; Along inflating circumferentially evenly distributing of ring, three sensing adjustment telescoping tubes cooperatively interact, and can realize continuous, the stepless adjustment that flexible paraboloid structure points to; For example, two length are constant in pointing to the adjustment telescoping tube, and during a length variations, flexible paraboloid structure can be realized rotating along axle; One motionless, and other two length cooperate when changing, and can realize along the rotation of two axles of quadrature, promptly points to change.
Beneficial effect
Antenna reflector of the present invention can carry out electromagnetic acceptance or emission, is easy to carry, light weight, volume is little, windage is little.
