Description
Technical field
The present invention relates to mobile satellite communication (communication in moving) antenna, especially dual polarization four ridge side's trumpet array antennas.
Background technology
Antenna Design for Satellite Communication in Motion is arranged on aircraft, train, automobile and naval vessel, forward the satellite of the communication information on the geo-stationary orbit of distance ground 36000km, because satellite density on geo-stationary orbit is high, when so antenna Design for Satellite Communication in Motion sends information to satellite, at first, day live width angle side lobe envelope must meet the technical requirement of International Telecommunication Association's regulation, surpasses this requirement, can do the normal operation of adjacent satellite on the sorrow geo-stationary orbit, International Telecommunication Association will forbid networking work.Secondly, the antenna orthogonal polarization isolation also must meet the requirement of the technical indicator of International Telecommunication Association's regulation, otherwise can disturb same user's normal operation that the satellite orthogonal polarization is multiplexing, can be forbidden networking work by International Telecommunication Association equally.These two technical requirements are most important condition that antenna Design for Satellite Communication in Motion must meet at emission state, otherwise the use that can't network.
Usually, the antenna Design for Satellite Communication in Motion form has: parabolic antenna (containing the burnt dual reflector antenna of ring), Kind of Shaped Paraboloid Antennas, waveguide slot array (antenna) array antenna, waveguide array antenna and phased array antenna etc.Wherein the waveguide array antenna receives much attention with the low section of its super-thin.
Summary of the invention
The object of the invention is to provide a kind of satellite communication in motion dual polarization four ridge side's trumpet array antennas that can be arranged on the high-speed motion carrier, this array antenna should realize that super-thin hangs down section, improve again wide angle side lobe envelope and the separation of cross polarization technical indicator of antenna, to meet the networking requirement of International Telecommunication Association to communication satellite antenna.
for achieving the above object, the technical solution used in the present invention is: this kind satellite communication in motion dual polarization four ridge side's trumpet array antennas, its formation includes, four ridge side's loudspeaker, orthomode coupler, perpendicular polarization waveguide power division/combinational network, horizontal polarization waveguide power division/combinational network, duplexer, tuner (LNB), up-conversion power amplifier (BUC), the polarization self-reacting device, it is characterized in that: described four ridge side's loudspeaker are the regular array arrangement of equidistant square, azimuth plane is got 32 row, pitching face is got 6 row, whole array surface has 192 four ridge side's loudspeaker, each four ridge side's loudspeaker bore is 38.60mm, each four ridge side's loudspeaker and an orthomode coupler (OMT) are combined into an integral body, array surface is of a size of 1204.20mm * 226.60mm.although the technical program has guaranteed that the antenna receiving-sending gain reaches technical requirement and pitching face physical size hangs down the requirement of section less than the super-thin of 300mm, but in order to leave necessary cabling space and allowance for perpendicular polarization waveguide power division/combinational network and horizontal polarization waveguide power division/combinational network, so four ridge side loudspeaker adjacent cells spacing d are taken as 37.6mm, be equivalent to d=1.53 λ ~ 1.82 λ, if four ridge side's loudspeaker are used as the array radiating element, and 192 radiating elements adopt again equidistantly square regular arrangement (as shown in Figure 11) of bidimensional, will produce large graing lobe at two face scanning real spaces so, at first its result causes large energy to be missed in graing lobe, make the antenna receiving-sending gain not reach technical requirement, next causes the large graing lobe of azimuth plane may cause capable and experienced sorrow to the adjacent star on synchronous satellite orbit, exceed the requirement of International Telecommunication Association to the wide angle side lobe envelope technical indicator that networks, so technical scheme requires further improvement.
Deficiency for above technical scheme, the present invention further improves technical scheme, horn mouth place at 192 four ridge side's loudspeaker, be provided with metal compensation Turbogrid plates, these metal compensation Turbogrid plates are divided into each four ridge side's loudspeaker four radiating elements of equal portions, namely make array antenna azimuth plane and pitching face unit bore all be divided into two, thereby make on whole aerial array face, formed 192 * 4=768 radiating element, these metal compensation Turbogrid plates possess two-dimentional merit and divide/combination function.It is all 0.77 λ l ~ 0.91 λ h that this technical scheme makes two face unit intervals in frequency band, during such two face constant amplitude homophase feeds, at real space, not there will be graing lobe, and the azimuth plane side lobe envelope also meets the requirement of International Telecommunication Association to the technical indicator of side lobe envelope.
