Abstract: A base station antenna comprises a plurality of columns of first radiating elements configured for operating in a first operational frequency band, each column of first radiating elements comprising a plurality of first radiating elements arranged in a longitudinal direction and an isolation wall positioned between adjacent columns of first radiating elements and extending in the longitudinal direction. The isolation wall comprises a frequency selective surface configured such that electromagnetic waves within the first operational frequency band are substantially blocked by the isolation wall.
