Abstract

An antenna array for simultaneous reception or for simultaneous transmission of electromagnetic waves having two linear, orthogonal polarizations has a decoupling device (17) between adjacent radiating element modules (1). This decoupling device is provided between two radiating element modules (1) which are adjacent in the attachment direction (21). The improvement is for a decoupling structural element (17) to be provided between two adjacent radiating element modules (1), which decoupling structural element (17) extends at least with its longitudinal component in the attachment direction (21), this longitudinal component having a length which is greater than or equal to 25% of the radiating element module separation (25) between the centers or bases (23) of the corresponding adjacent radiating element modules (1).
