Want frequency range, it is adaptable to power overload demand.
For solving the problems referred to above, this utility model is achieved through the following technical solutions:
A kind of VHF Band Airborne broad-band antenna, including radiant body, feeds socket and covers at outside radiant body
Antenna house, be provided with mounting seat in the bottom of antenna house, described antenna house and radiant body pass through asphalt mixtures modified by epoxy resin
Fat is tightly connected and is integrated, and described radiant body is supported in antenna house by support, and described feed socket sets
In the lower section of mounting seat, described radiant body includes radiating core, oval feed structure and loading on radiation
The horizontal cross bar at core top, one end of described oval feed structure is connected with radiation core, its other end leads to
Cross the feed connection point arranged to be connected with the N connector on feed socket.
In such scheme, described radiant body is additionally included on radiation core the bending structure arranged, described bending
Structure connects as one with horizontal cross bar, oval feed structure and radiation core.
In such scheme, for making the antenna of this structure in use, neither affect the work of top horizontal cross bar
While work, the feed nor affecting on antenna bottom connects, and preferably described bending structure is located at radiation core
Middle part and bottom between position.
In such scheme, for preventing the antenna of this structure in use process by rainwash, affect antenna
Electrical connection i.e. signal transmission, preferably also set up with the fixed connection place of mounting seat in the bottom of antenna house
There is waterproof layer.
In such scheme, described horizontal cross bar can be metal bar.
In such scheme, described antenna height is 480mm.
Designing according to the structure of this antenna, the working band of described antenna can cover the main frequency range of VHF.
The beneficial effects of the utility model are:
1) antenna of the present utility model is at top-loaded one horizontal cross bar of radiation core, can reduce antenna defeated
Enter the capacitive reactance of end, thus reduce antenna bottom loss, to reach to improve the purpose of antenna performance；
2) the oval feed structure used, required for the feed length that takies and area be less than tradition
Wedge shape or triangle feed structure, be so conducive to reducing the height of antenna, make the space that antenna occupies
Less, it is of value to the miniaturization work of airborne antenna；
3) radiation core segment is set to bending structure, is possible not only to meet the requirement of antenna miniaturization, also
Carried out the electrical length of extension antenna by bending antenna, thus reduce the resonant frequency of antenna；
4) it is not required to use attenuator and match circuit, still ensure that the coupling in antenna broad frequency range
Reliability, simple in construction, with low cost, it is easier to promote.
