Abstract
An airborne tubular antenna comprises an L-shaped spiral radiator. The spiral radiator is positioned in an antenna radiant tube and a hollow support frame which are perpendicular to each other, a spiral line on the spiral radiator is divided into three sections in the antenna radiant tube, each section of thread pitch is different, two neighboring sections of spiral lines are hinged, and the spiral line on the spiral radiator is connected with a tail connector of a radio frequency cable. Since a spiral line technology is introduced in the antenna, by the aid of a spiral line model, within a limited structure size of the antenna, length of an antenna radiator can be increased, and radiation efficiency of short-wave communication can be improved. A partial spiral radiator is mounted in the antenna support frame, so that a radiation pattern of the antenna is close to be omnibearing, and the problem of telecommunication of the antenna is solved effectively according to the principle. The antenna has the advantages of convenience in mounting and dismounting, non-maintenance, high reliability and the like.
Description
Technical field
The invention belongs to antenna technical field, be mainly used in helicopter-mounted radio station, relate to a kind of airborne tubulose antenna.
Background technology
At present, China's airborne antenna mostly is wire antenna, but wire antenna has the following disadvantages: cable wire often needs adjustment elasticity, cable wire steel wire fracture phenomenon, spring failure, the be full of cracks of cable wire overcoat easily to occur and comes off, and steel wire causes the bad phenomenon such as normal operation of other airborne equipments of harmonic effects that resonance produces because of the aircraft vibrations.China's airborne antenna is affected by this for a long time, becomes long-term denouncing of the airborne communication system of China.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of airborne tubulose antenna, operating frequency is 1.6MHz～30MHz, has solved that airborne short-wave radio set uses the fracture of antenna, the overcoat that comes off, steel rope fault, the problem of the interference harmonic wave that produces because of resonance.
To achieve these goals, the technical solution used in the present invention is:
A kind of airborne tubulose antenna, the helical form radiant body 3 that comprises L-type, helical form radiant body 3 is arranged in orthogonal aerial radiation pipe 1 and hollow support frame 2, helix 4 on the helical form radiant body 3 is divided into three sections in aerial radiation pipe 1, every section pitch is different, helix 4 between adjacent two sections is hinged, and the helix 4 on the helical form radiant body 3 connects the minor details connector of radio frequency cable 5.
The internal diameter of described helix 4 is between φ 15～φ 25, and pitch is at 10mm～18mm Transforms.
Being first paragraph apart from hollow support frame 2 nearest helixes 4, is second segment secondly, farthest be the 3rd section, then the pitch of first paragraph helix 4 is 18mm, the pitch of second segment helix 4 is 14mm, the pitch of the 3rd section spiral line 4 is 10mm.
Described hollow support frame 2 is fixed on the aerial radiation pipe 1 by shop bolt, and flange face keeps coaxial in the same side.
Described helix 4 is wound with wire at the articulated position place.
Be parallel to described hollow support frame 2 and be provided with two other independent support frame 6, hollow support frame 2 equates with two independent support frame 6 mutual spacings, common supporting antenna radiant tube 1.
The present invention compared with prior art, the helix technology is incorporated among the antenna, the helix pattern can be in the limited physical dimension of antenna, (antenna length is about 20m to have increased the length of antenna radiator, reach the quarter-wave of 3～4MHz), therefore promoted the radiation efficiency of short wave communication.And the spiral helicine radiant body of part is housed in the antenna support frame, so the antenna pattern of antenna is near omnidirectional.Antenna adopts this principle to solve emphatically the telecommunication problem of antenna.This antenna has easy accessibility simultaneously, and is non-maintaining, the reliability high.
