Metamaterials are structures specifically designed to create properties not found in natural materials. A new metamaterial presented in the journal Communications Engineering could allow satellites to transmit more data, enhance remote sensing and improve signal quality.
Existing antennas operate in linear polarization, which can cause signal loss due to misalignment between the transmitter and receiver. The new metamaterial converts linear polarization to circular polarization, improving communication quality and resistance to atmospheric effects such as rain and ionospheric interference.
Just 0.64 mm thick, the metamaterial is made from copper cells and is easily manufactured using conventional printed circuit boards.
