Abstract

The utility model relates to an inflatable antenna made of an airtight flexible material. The antenna part is electroplated with a conducting film fixed to a base and connected with the base by gas. The utility model is convenient in use and carry and folding.

Description

Inflatable antenna

The utility model relates to a kind of gas-filled type antenna.

Existing antenna is made with metal and other hard material mostly, and certain volume and weight is arranged.Use for the unfixed short-term in places such as field work or military operation, very not convenient when carrying.

The purpose of this utility model is that a kind of portable gas-filled type antenna will be provided.

The utility model is achieved in that the manufacture craft of utilizing the gas-filled type utensil, and air-locked flexible material is made the antenna and the base of different shape, and antenna surface lining one deck conducting film also is fixed on the respective seat of supporting role with it that gas is communicated with.Only need inflate during use and get final product, the time spent can not bleed off gas, and folding gets up.

The utility model has the advantages that:

1. easy to use and carry.

2. in light weight, folding not shared space of time spent is little.

3. can be general with the respective antenna of present use.

4. saving metal material.

Below in conjunction with accompanying drawing concrete structure of the present utility model is further described.

Fig. 1 is the element antenna schematic diagram.

Fig. 2 is the helical antenna schematic diagram.

Fig. 3 is the parabolic antenna schematic diagram.

Fig. 4 is the circular loop antenna schematic diagram.

Fig. 5 is the installation exploded view of terminals.

With reference to Fig. 1, be example with the typical element antenna of Unit three.

Reflector 1

Folded dipole 2

Director 3

Base 4

Charging connector 5

Terminals 6

Air vent hole 7

Reflector, folded dipole, director are fixed on the rectangle base according to certain proportional sizes.Two air vent holes are respectively opened at the middle part of reflector and director symmetrically; Two air vent holes are respectively opened at the middle part of folded dipole and two ends symmetrically, and relative up and down.Air vent hole on the relevant position of these air vent holes and base is connected, and gas is inflated by these air vent holes.Charging connector is positioned at the appropriate location of base.The height of base is slightly less than the interior height of folded dipole.At the two ends of folded dipole terminals are arranged respectively.

The helical antenna base 1 of Fig. 2 is a cylinder, and cylindrical diameter is the internal diameter of helical antenna, and the soft material 2 of lining conducting film is processed into the long slice of certain width, sticks on the face of cylinder from the terminals 3 beginnings pitch in accordance with regulations that is positioned at the cylinder bottom.The height h of helical antenna is lower than cylindrical height L.Charging connector 4 is arranged on cylindrical top.

The parabolic antenna of Fig. 3 is shaped as angle less than 90 ° L type, and lining has the parabola 1 of conducting film on the inboard inclined-plane of L type, and the distance of focal point F is parabolic height h and surface width d sum, and the bottom surface of L type plays a supportive role.Charging connector 2 is positioned at the appropriate location of L type bottom surface.

The two ends of the circular loop antenna 1 of Fig. 4 respectively have an air vent hole 5 to fix with base 2 and gas is communicated with, and terminals 3 are positioned at the two ends of circular loop antenna, and charging connector 4 can be positioned at the appropriate location of base 2.

Before processing, installation method such as Fig. 5 should be installed the terminals of each antenna among Fig. 1, Fig. 2, Fig. 4 earlier.Among the figure: nut 1, rubber washer 2, metal washer 3(is positioned at the antenna outer surface), conduction soft material 4, what be positioned at the antenna inner surface is metal washer 5, rubber washer 6, screw 7.Metal washer 3 is the wiring leading-out end, and its ledge has a hole.

The material of antenna and base can be plastic film, waterproof cloth, rubberized fabric etc.But the conducting film lining is at the outer surface of antenna, but also lining at the inner surface of antenna.
