3 Innovative Uses of Composite Manufacturing for Waveguides and Antenna Components

 In Education

Composite manufacturing has revolutionized how waveguide and satellite antenna components are made in multiple industries. From spacecraft technology and satellite communications to aerospace and helicopters, composite materials have been utilized to reduce weight, increase efficiencies, and enhance the durability of waveguides and antennas. 

Spacecraft technology

Composite materials are widely implemented in spacecraft structures, allowing engineers to create more efficient, lighter-weight vehicles. The innovations in composite materials have greatly improved the manufacturing of space horn antennas. These space horn antennas are essential in space communication systems.

Until recently, all parts of these horn antennas were manufactured from aluminum alloys. The metal horn makes up over 60% of the total weight of the entire antenna’s structure. This can drastically affect the total mass of a spacecraft when these large antennas are attached. It quickly becomes evident that reducing the weight of these horn antennas is essential for creating efficient spacecraft. 

Advanced composite materials like carbon-fiber reinforced plastics (CFRP) are widely used in manufacturing space horn antennas. Carbon-fiber reinforced plastics make these horn antennas significantly lighter than metal options, and CFRP-made horn antennas drastically outperform metal antennas in mass reduction. Using composite materials to create horn antennas can make the entire spacecraft more lightweight and efficient.

Aerospace and helicopter antennas

Carbon composite materials are now widely used to manufacture aerospace and helicopter antennas. These materials reduce weight, increase immunity to corrosion, and have high stability within a wide range of temperatures. They also have a long lifetime and unparalleled durability-to-weight ratios. 

Graphene-containing carbon composite materials (GCMs) in waveguides and antennas is a promising innovation. GCMs in waveguides can significantly improve their reflection and scattering properties. These innovative GCMs also enhance the directivity of electromagnetic waves, increase the antennas’ gain, reduce weight, and even suppress interference between the antenna elements. 

Graphene-containing carbon composite material antennas and waveguides have substantial advantages over their metal counterparts. These GCM antennas may eventually replace metal versions due to the vast reductions in weight and cost.

Satellite communication antennas

Satellite radio frequency ground systems face increasing technical challenges as satellite communication networks move to higher-frequency ranges. In addition, ground systems composed of steel and aluminum are more susceptible to structural distortions, while environmental factors like rain can degrade signal performance at these higher frequencies.

Structural issues can be significantly reduced by manufacturing satellite communication antennas with composite carbon fiber. A carbon-fiber design minimizes thermal, wind, and gravity load distortion. It also reduces shipping weight, improves performance in all frequencies, and can be installed at faster rates. These composite carbon fiber radio frequency antennas are designed to meet the changing needs of advanced RF ground systems.
