NASA successfully tests 3D printed antenna for future space missions, improving communication systems.
An important part of space communication, the development of 3D printed antennas by NASA has developed substantially. Engineers from NASA's Near Space Network and the Electronics 3D Printing group at Goddard Space Flight Center have recently designed and tested a 3D printed antenna using Fortify's technology. The demonstration under this project is meant for low-cost, efficient antennas meeting the general requirements of the industry for future space missions. It was launched aboard a weather balloon from NASA's Columbia Scientific Facility in Texas. The antenna marked a major milestone in creating affordable communication equipment for space exploration.
One of the major challenges in manufacturing 3D printed antennas is the integration of materials with specific electromagnetic properties while ensuring adequate conductivity for signal transmission. The NASA team addressed this by using a ceramic-filled polymer material that allowed for low electrical resistance and improved signal tuning. The antenna was optimized for data transmission, and its design was tested with NASA's relay satellites before being subjected to high-altitude tests on the weather balloon.
The magneto-electric dipole-type antenna includes a doughnut-shaped radiation pattern, which is commonly used in telecommunication. It was printed using Fortify's Flux One printer to allow the engineers to have full control over the electromagnetic and mechanical properties of the circuit. The measurements were carried out in an electromagnetic anechoic chamber of the Goddard Center in Maryland; interference was eliminated for accurate performance measurement. It was then tested in the field at high altitudes, where it passed with flying colors, successfully sending and receiving data at 100,000 feet.
This development opens new possibilities for future space missions. Additive manufacturing enables rapid prototyping, material flexibility, and improved antenna designs, ultimately enhancing communication systems for NASA's missions.
