Publication number: 20240332802Abstract: An antenna assembly, an apparatus having the antenna assembly, and a method of manufacturing the antenna assembly are disclosed. Antenna performance in, e.g., mobile devices is improved via an antenna assembly which allows wide-angle beam scanning across a wide frequency bandwidth. Wide beam coverage may in turn contribute to improving multi-surface spherical beam coverage, such as in broadside direction and endfire direction, and to reducing the amount of needed antenna modules. A tightly-coupled dipole array exhibits wide operating frequency bandwidth characteristics.Type: ApplicationFiled: June 12, 2024Publication date: October 3, 2024Inventors: Ruiyuan Tian, Konstantin Sokolov, Alexander Khripkov, Timofey Kamyshev, Janne Ilvonen, Zlatoljub Milosavljevic, Hanyang Wang, Joonas Krogerus
