Researchers at MIT have invented a reconfigurable antenna, dubbed a 'meta-antenna,' that can dynamically change its frequency range by altering its shape. Made from auxetic metamaterials, the antenna's resonance frequency shifts based on its deformation, allowing for versatility in wireless communication applications.
MIT researchers have developed an antenna that can adjust its frequency range by physically changing its shape.This newly designed reconfigurable antenna device has been dubbed “meta-antenna.” Instead of standard, rigid metal, this antenna is made from metamaterials — special engineered materials whose properties are based on their geometric structure.
Metamaterials allow us to get those different states from only one structure,” added AlAlawi.In terms of its construction, the meta-antenna is built with a non-conductive, or dielectric, layer sandwiched between two conductive layers. It was created by laser-cutting a dielectric layer from a rubber sheet, which was then topped with a conductive spray-painted patch to form a resonating “patch antenna.
