Description

Military and civil dual-purpose integrated Beidou third-generation antenna in complex environment

Technical Field

The utility model relates to an antenna technology, especially one kind is applied to in the big dipper third generation terminal antenna subassembly and the antenna system of military and civilian integration demand to and be applied to relevant fields such as on-vehicle, shipborne, water conservancy, observing and controlling and military affairs.

Background

With the development and application of the Beidou third-generation navigation technology, on a loading platform, particularly on a vehicle-mounted platform, the space is very small, the requirements on light weight and small size are met, more important requirements are that the low elevation gain is high, the outfield environment is very complex, the interference of other frequency bands and high power is realized, the multipath problem and the problem of coupled signals are solved, and meanwhile, the Beidou third-generation navigation technology is also applied to military and civil platforms.

The most common method in the industry is to adopt ceramic composite materials, when the space is very small, the effect of the ceramic composite materials is very small, and microstrip rectangular radiation used by the ceramic composite materials is the most basic material with the widest application, and simultaneously, the ceramic composite materials have low price and have unique application in civil platforms. Therefore, an integrated composite antenna which is low in price, can be applied to a civil platform and can be provided with a military platform in the aspects of indexes and use environments is very urgently needed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at: aiming at the existing problems, a military and civil integrated Beidou third-generation antenna applied to a complex environment is very needed.

The technical solution of the utility model is that:

the antenna comprises a radiator 1, a ground plate 2, a radiation layer 3 and a short circuit column 4, wherein an inner core of an output connector 5 penetrates through the radiator 1 to be connected with the radiation layer 3, and an outer shell of the output connector 5 is connected with the ground plate 2. The radiator 1 is made of special materials resistant to high temperature and high pressure, so that the antenna can adapt to a military environment with high temperature and high impact and a civil environment resistant to weather, can be mounted on the surface of equipment by screws and can be adhered to the surface of the equipment, and an integrated antenna assembly for military and civil use is achieved. The utility model has the characteristics of simple structure, with low costs, adaptability are very strong etc, moreover can be anti natural weather's such as rain fog influence, the wide application in the relevant field of military and civil wireless microwave communication.

Compared with the prior art, the utility model the advantage lie in:

because the utility model discloses a short-circuit column has further widened the beam width of antenna as the partly of radiator, has improved low angle of elevation gain, has reduced the volume and the weight of antenna simultaneously widely.
