Researchers create compliant mechanism-enabled, reconfigurable antenna. Reconfigurable antennas — those that can tune properties like frequency or radiation beams in real-time, from afar — are integral to future communication network systems, like 6G. But many current reconfigurable antenna designs
Researchers illustrated and designed a circular, iris-shaped patch antenna prototype using commercial electromagnetic simulation software. Though the prototype is only slightly larger than a human palm, the technology can be scaled to the integrated circuit level for higher frequencies or increased in size for lower frequency applications, according to researchers.
“Just like a chameleon triggers the tiny bumps on its skin to move, which changes its color, a reconfigurable antenna can change its frequency from low to high and back, just by configuring its mechanical properties, enabled by the compliant mechanism,” said co-author Sawyer Campbell, associate research professor in EECS.
“Origami antenna designs are known for their compact folding and storage capabilities that can then be deployed later on in the application,” Mackertich-Sengerdy said. “But once these origami folded structures are deployed, they usually need a complex stiffening structure, so that they don’t warp or bend. If not carefully designed, these types of devices would suffer environmental and operational lifetime limitations in the field.
Though the prototype — designed to target a specific frequency for demonstration — is only slightly larger than a human palm, the technology can be scaled to the integrated circuit level for higher frequencies or increased in size for lower frequency applications, according to researchers.
