Abstract: The present disclosure relates to a radiating element, which includes: a dipole arm configured to emit first electromagnetic radiation within a pre-determined first operating frequency band; and a parasitic radiator, configured such that a first induced current induced on the parasitic radiator within a second operating frequency band at least partially cancels a second induced current induced on the dipole arm within the second operating frequency band. In addition, the present disclosure relates to a base station antenna, including: a first radiating element array, configured to emit first electromagnetic radiation within a pre-determined first operating frequency band, and at least a part of first radiating elements in the first radiating element array is constructed as radiating elements according to the present disclosure; a second radiating element array, configured to emit second electromagnetic radiation within a pre-determined second operating frequency band.

Abstract: A radio frequency device, multi-band phase shifter assembly, an antenna system and a base station antenna in which metasurface decoupling elements between transmission lines are provided. For example, a radio frequency device may include: a substrate; a first transmission line printed on a first major surface of the substrate; a second transmission line adjacent the first transmission line printed on the first major surface of the substrate; a metasurface decoupling element printed on the first major surface of the substrate, where the metasurface decoupling element is arranged between the first transmission line and the second transmission line.
