An Introduction for Flyaway Antenna Structure

In order to embody portable performance, make sure the flyaway antenna characteristics of light weight, small geometry size in package, quick and convenient assembly, high precision of reassembly in the design. For flyaway antenna introduction, please visit the website: Flyaway Antenna Introduction.

In order to reduce flyaway antenna weight, carbon fiber composite material is adopted in the reflector. The reason is the carbon fiber composite materials possess characteristics of light weight, high modulus, and a low coefficient of thermal expansion. There are various structures to make flyaway antenna reflector with carbon fiber. And honeycomb sandwich construction is widely adopted because of high rigidity, light weight and convenient to do the production. Flyaway antenna adopts honeycomb sandwich construction with aluminum. Carbon fiber itself possesses conductivity, but not as well as metal. Carbon fiber becomes poor conductor because resin exists basically. So the flyaway antenna reflector needs metallization. Method of metal ion transference is introduced to metalize the portable antenna. The shape of flyaway antenna reflector is optimized in design, and the geometric dimension is reduced so as to pack conveniently. The eternal outline of the flyaway antenna reflector is quadrilateral, which consists of four 350*350 small quadrilateral reflector. The illustrated diagram of flyaway antenna panel is shown in Fig 3-43. 


 

There are location and fast connection device between all block panels to make sure of quick assembly and high precision reassembly. And there needs no tool when assembling. The weight of flyaway antenna reflector is less than or equal to 7kg.

Operating Principle Of Flyaway Antenna

The type of antenna consists of reflector, pedestal and feed system. And its operating principle is shown in Figure 3-47.

Microwave signal sent by high-power amplifier is transferred onto feed system through waveguide feed, and then it is reflected onto reflector from feed radiation. The reflector is rotary paraboloid and the feed is placed in the focal point of rotary paraboloid. After antenna reflector’s reflection, electromagnetic wave radiates towards free space and forms beam. Spatial electromagnetic signal from space is reflected by antenna reflector and converged on the feed, and then transmitted to duplexer through waveguide feeder. The signal which antenna receives is amplified and sent to the receiver by the connection of amplifier and duplexer end. Waveguide feeder connects duplexer with flange plate.
