Using theoretical knowledge based on origami theory mechanical dynamics and antenna array principles the researchers built a small lightweight and reconfigurable antenna for CubeSat depending on operational mode selected.
New origami antenna. Origami technology offers a very good and low cost alternative to design flexible and deployable antennas because origami folding can easily miniaturize antenna size making them more suitable for transportation and easily deployed at their desired location 248 This is particularly useful for applications that require large antennas when in use. Furthermore multi-radii origami antennas are proposed analyzed fabricated and validated and they exhibit improved circular polarization performance and wide bandwidths. Researchers are using the geometry of paper folding to come up with futuristic antennas that can retract and compress.
This could potentially mark the beginning of a new era in satellite communications. As a proof-of-concept an E-textile accordion-dipole is fabricated and shown to vary its resonance frequency. One example is a foldable v-shaped antenna 15 which was inkjet-printed onto a substrate the authors called nanopaper using silver nanowire ink.
Antennas based on origami cylinders are developed and validated. A painter and sculptor since she was a child Florida International University student Briana Gonzalez brings an artistic sensibility to her work at a new FIU center to design origami antennas. Foldable radial mounted Antennas to complement RemoteTechs needs mostly inspired by NASAs TDRS.
To test the origami prototype as a reflector antenna the flat paperboard surfaces of the origami prototype structure were metallized with an adhesive backed conductive copper tape. The resonant frequency of the antenna was altered by folding the nanopaper which changed the length of the antenna lines. Printing precise silver-based patterns on a type of foldable origami called Miura-Ori researchers from the Georgia Institute of Technology demonstrated frequency selective paper-based antennas that could be tuned continuously as the origami shape was expanded or contracted.
Developed by Oxford Space Systems in partnership with ESA this origami-inspired antenna is equal in length to the shoebox-sized satellite hosting it part of a growing constellation of nanosatellites providing Internet of Things services around the globe. In a brand-new study scientists from Korea and the USA have revealed a novel antenna design for use in CubeSat nanosatellites using state-of-the-art communi. To enable mechanical flexibility and robustness the antennas are fabricated using automated embroidery of silver-coated polymer E-threads.
There are two dish antennas at the moment a large antenna ranging at 350Gm for most of Kerbol system and a smaller on ranging 69Gm reaching all of Kerbols inner rocky planets. For example a deployable origami antenna in. This antenna can change its operating frequencies by changing its height.
We introduce a new class of Origami-based tessellated antennas whose RF characteristics can be self-tuned by reconfiguration of the antenna shape. Novel fabrication methods of origami antennas are presented with detailed geometrical analysis. A novel helical antenna that sprang from a container the size of a tuna can is now operational in orbit.
MIAMI Fla - The Air Force Office of Scientific Research AFOSR has awarded Florida International University FIU an additional 482 million to expand its research on origami antennas. Based on which origami antennas can be built such as conical log spiral antenna. Also analytical equations for the design of such antennas are derived based on an equivalent model of a standard.
With a high electrical conductivity of 596 10 7 Sm 1 copper tape can support high surface current density ultimately affecting the far-field radiation patterns of the antenna. Engineers are redefining the limits of origami and constantly discovering new algorithms that create advantageous applications 911. Specifically the mechanics of folding has successfully been leveraged in many antenna systems.
Although there was a plastic column to support the antenna the folded and unfolded antenna didn t have a stable geometry. Origami unfolds a new world of shape-shifting electronics. For example origami antennas have demonstrated reconfigurability of frequency 1214 patterns 15 16 and.
An Origami Reconfigurable Axial-Mode Bifilar Helical Antenna. Air Force invests 48M in FIU origami antenna technology for aircraft UAS satellites. A reconfigurable axial-mode helix antenna was built in 2 which used a shape memory alloy spring actuator to adjust its height.
Air Force is investing nearly 5 million in origami or foldable and reconfigurable antennas to enable new aerospace and tactical systems for communication and sensing in aircraft and satellite applicationsInspired by the Japanese art of paper folding origami electromagnetic systems. A painter and sculptor since she was a child Florida International University student Briana Gonzalez brings an artistic sensibility to her work at a new FIU center to design origami antennas. The lightweight antennas are designed to fold like origami for easy packing making them useful for spacecraft and for soldiers who ordinarily lug heavy communications equipment.
