Abstract
The utility model relates to a miniaturized structure of satellite anti -interference antenna unit, including the antenna house, the antenna reflecting plate, a cover plate, the main structure cavity, the bottom plate, there is a cross slab to cut apart the cavity become in the middle of the main structure cavity, two lower chambeies, the several capsule body is respectively separated into to upper and lower intracavity, and the passageway is put to the radio frequency low noise and the unit is combined to the frequency in order to place respectively, the several apron is fixed in the baffle up end of the little box body of several respectively, the antenna reflecting plate is arranged the apron in and is gone up and be fixed in on the main structure cavity, the antenna reflecting plate has the trompil of placeeing antenna body, the antenna house is fixed on arranging the main structure cavity in. The utility model has the beneficial effects of, small, the interface headspace is many, has satisfied the miniaturized demand of anti -interference antenna, is applicable to the arctic -alpine environment of high temperature.
Description
Technical field
This utility model relates to a kind of for aircraft satellite navigation system anti-interference antenna unit, particularly to the miniaturization structure of a kind of satellite anti-interference antenna unit.
Background technology
All the time, satellite anti-interference antenna size and weight are bigger than normal, carry, install extremely inconvenient, are badly in need of minification, deduct product weight on working strength basis ensureing.
Summary of the invention
In view of prior art Problems existing, this utility model provides the miniaturization structure of a kind of satellite anti-interference antenna unit, compact package mode taked by structure and radio circuit, reasonably utilize the confined space, radiofrequency low-noise puts the structure of passage and the comprehensive unitary space multiplexing of frequency, concrete technical scheme is, a kind of miniaturization structure of satellite anti-interference antenna unit, including antenna house, antenna-reflected plate, cover plate, main structure cavity, base plate, there is a diaphragm plate that cavity is divided in the middle of main structure cavity, lower two chambeies, respectively it is separated into several little box body in upper and lower cavity and puts passage unit comprehensive with frequency to place radiofrequency low-noise respectively, several cover plates are individually fixed in the dividing plate upper surface of several little box body, antenna-reflected plate is placed on cover plate and is fixed on main structure cavity, antenna-reflected plate has the perforate putting antenna body, antenna house is placed on main structure cavity and fixes.
Of the present utility model having the technical effect that, volume is little, and interface headspace is many, meets anti-interference antenna miniature requirement, it is adaptable to the environment that high temperature is high and cold.
Accompanying drawing explanation
Fig. 1 is structural blast figure of the present utility model.
Fig. 2 is main structure cavity top view of the present utility model.
Fig. 3 is outline drawing of the present utility model.
Detailed description of the invention
Such as Fig. 1, 2, shown in 3, for a kind of structure for aircraft satellite navigation system anti-interference antenna unit, mounting opening size is only 120mm*120mm, antenna thickness 31.5mm, lightweight about 1kg, including antenna house 1, antenna-reflected plate 2, cover plate 3, main structure cavity 4, base plate 5, there is a diaphragm plate that cavity is divided in the middle of main structure cavity 4, under, two chambeies, upper intracavity is separated into four little box body 4-1, place LNA and channel module respectively, four cover plates 3 are individually fixed in the dividing plate upper surface of four little box body 4-1, antenna-reflected plate 2 is placed on cover plate 3 and is fixed on main structure cavity 4), antenna-reflected plate 2 has the perforate putting antenna body, antenna house 1 is placed on main structure cavity 4 and fixes.
This utility model can reach similar anti-interference antenna technical performance index, it is adaptable to the environment that high temperature is high and cold, and small product size is little, lightweight, spare interface space.
