Abstract
The invention provides a body-mounted flat plane antenna for an inflatable satellite, belonging to the technical field of antennas. The body-mounted flat plane antenna comprises a reflection plane, an antenna module, a support ring and a support tube, wherein the reflection plane is fixed in a ring of the support ring, the antenna module is fixed at the lower side of the reflection plane, and the support tube is fixed at the upper side of the reflection plane. The invention solves the problems that the antenna caliber is difficult to enlarge due to the installation mode that the antenna is used as an accessory outside the satellite, and the precision and strength of signal transceiving of the whole satellite are greatly reduced due to the reduction of structural vibration base frequency. Compared with the traditional installation mode that the antenna is used as the accessory of the satellite, the body-mounted flat plane antenna is beneficial to enlarging of the effective caliber of the antenna and is also beneficial to improving of the whole structural rigidity and vibration base frequency of the satellite and greatly improving of the whole dynamics property of the satellite and the precision and strength of signal transceiving of the satellite.
Description
Technical field
The present invention relates to a kind of body dress formula flat plane antenna for gas-filled satellite, belong to the satellite technology field.
Background technology
Existing antenna for satellite is all that the form with external annex is installed on satellite.Yet along with the continuous lifting of satellite function, increasing for the dimensional requirement of antenna aperture, the technology that this mounting means of antenna has caused satellite launch on the one hand is a very large restriction for the increase of caliber size; On the other hand, antenna is as external annex, and size has brought the problem of the flexible increase of structure also to become more serious after improving thereupon.Because the structural vibration fundamental frequency is lower, makes the surface accuracy of satellite antenna be difficult to guarantee, thereby cause the precision of whole satellite receiving and transmitting signal and intensity greatly to reduce.
Summary of the invention
The objective of the invention is cause antenna aperture to increase hard problem as the mounting means of satelloid outer attachment and make the structural vibration fundamental frequency reduce the precision of the whole satellite receiving and transmitting signal that causes and the problem that intensity reduces greatly in order to solve antenna, and then a kind of body dress formula flat plane antenna for gas-filled satellite is provided.
The objective of the invention is to be achieved through the following technical solutions:
The present invention includes: reflecting surface, Anneta module, support ring and stay pipe, be fixed with reflecting surface in the ring of support ring, Anneta module is fixed on the downside of reflecting surface, and the upside of reflecting surface is fixed with stay pipe.Described Anneta module is sticked on microstrip antenna thin film dielectrics substrate by the microstrip antenna paster and consists of.The edge of reflecting surface is connected with support ring around its peripheral inflatable deployable.Support ring is connected with the inside of the housing of gas-filled satellite, and the stay pipe by inflatable deployable is connected with the satellite nuclear phase at gas-filled satellite center.Also be connected with the housings support pipe between the housing of satellite core and gas-filled satellite, formed supporter by the support ring of inflatable deployable and the stay pipe of inflatable deployable.
The invention has the beneficial effects as follows: the invention solves antenna and cause antenna aperture to increase hard problem as the mounting means of satelloid outer attachment and make the structural vibration fundamental frequency reduce the precision of the whole satellite receiving and transmitting signal that causes and the problem that intensity reduces greatly.The present invention adopt body dress formula antenna than antenna in the past as the mounting means of satelloid outer attachment, very favourable to the effective aperture that increases antenna, and be conducive to improve the overall rigidity of structure of satellite and fundamental vibration frequency, precision and the intensity greatly having improved the integral power characteristic of satellite and improved the satellite receiving and transmitting signal.

Embodiment
The specific embodiment of the invention provides a kind of body dress formula flat plane antenna for gas-filled satellite (is seen Fig. 1 ~ Fig. 3), comprise: reflecting surface 1, Anneta module 2, support ring 3 and stay pipe 4, be fixed with reflecting surface 1 in the ring of support ring 3, Anneta module 2 is fixed on the downside of reflecting surface 1, and the upside of reflecting surface 1 is fixed with stay pipe 4.
Reflecting surface 1 of the present invention is to be made of inflatable structure, and the shape of described reflecting surface 1 can be rectangle or polygon or annular.The edge of reflecting surface 1 is connected with support ring 3 around its peripheral inflatable deployable.Support ring 3 is connected with the inside of the housing 7 of gas-filled satellite, and the stay pipe 4 by inflatable deployable is connected with the satellite core 5 at gas-filled satellite center.Also be connected with housings support pipe 6 between the housing 7 of satellite core 5 and gas-filled satellite, formed supporter by the support ring 3 of inflatable deployable and the stay pipe 4 of inflatable deployable.Reflecting surface 1 is pasted Anneta module 2 on the one side of satellite outside, described Anneta module 2 is sticked on microstrip antenna thin film dielectrics substrate by the microstrip antenna paster and consists of.
The design of the microstrip antenna paster in Anneta module adopts digital wave formation technology to control wave beam and radiation direction, so that antenna satisfies the performance index such as frequency bandwidth, angle of coverage.The housing of reflecting surface and gas-filled satellite all adopts can just be changed flexible composite and consist of, and collapsible, expansion, structure are just changed.Under the unaerated deployed condition, flat plane antenna is along with gas-filled satellite folds, and after the gas-filled satellite inflation, reflecting surface is along with gas-filled satellite launches, the expansion of supporter has further driven the antenna expansion, forms after structure is solidified to reach the flat plane antenna that required surface accuracy requires.
Antenna aperture of the present invention is large, dynamic performance good, satellite overall assembly degree is high, detection performance good, folding efficiency is high, the emission volume is little, total quality is light.Antenna aperture can obtain greatly larger gain, farther detection range and better target discrimination.Body dress formula antenna is conducive to improve the overall dynamics of satellite, be convenient to during the space motion of satellite the attitude adjustment, become the operation such as rail.The fundamental vibration frequency of body dress formula antenna improves, and causes thereby greatly reduce structure the possibility damaged due to vibration, has guaranteed the surface accuracy of satellite antenna, and precision and the intensity of whole satellite receiving and transmitting signal improve greatly.
The above; only be the better embodiment of the present invention; these embodiments all are based on the different implementations under general idea of the present invention; and protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement are within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
