Antenna array
First Claim
1. An antenna array for simultaneous reception and/or simultaneous transmission of electromagnetic waves having two linear orthogonal polarizations, comprising:
- a plurality of radiating element modules including at least two radiating element modules adjacent one another along a straight line defining a connection direction therebetween;
the radiating element modules each having a radiating element arrangement for simultaneous reception and/or transmission of electromagnetic waves having two orthogonal polarizations defining two mutually orthogonal polarization planes;
said connection direction of the antenna array being offset with respect to the alignment of the two mutually orthogonal polarization planes of the two orthogonal polarizations to be received and/or transmitted;
a decoupling device between said two adjacent radiating element modules;
said decoupling device including a decoupling element having a longitudinal component parallel to said connection direction of said two adjacent radiating element modules; and
said longitudinal component of said decoupling element having a length equal to or greater than 25% of a separation distance between centers of said adjacent radiating element modules.

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).
