Radisol from Murata to suppress interference between nearby antennas

Murata launched a product called Radisol – an innovative product designed to suppress interference between nearby antennas with low insertion loss, improving isolation and antenna radiation efficiency. This world-first solution is specifically engineered to meet the demands of compact modern devices like smartphones and wearables, offering benefits such as reduced power consumption, miniaturized construction, and enhanced communication quality. In addition, Radisol has been adopted by Motorola Mobility LLC (Headquarters: Libertyville, Illinois, USA, President: Sergio Buniac), in the new Edge series of smartphones scheduled to be released in August 2024. Motorola has realized a method of improving the characteristics of Wi-Fi antennas by using Radisol. 　 As the demand for smaller smartphones and wearable devices grows, the number of antennas is also increasing to accommodate the expanding range of communication methods and bands. Additionally, MIMO technology to improve communication quality and speed is encouraging an increase in the number of antennas, while new designs such as foldable smartphones are encouraging antenna crowding. This has posed new difficulties, specifically the implications on antenna isolation and the decline in antenna effectiveness, as the interference of nearby antennas leads to a decrease in radiation efficiency. 　 Although discrete filters are a c...
