A prototype array of dual polarized connected dipoles has been manufactured. The feed structure is composed by two orthogonal 8×8 elements for each polarization (128). The operational frequency ranges from 6 to 9 Ghz (40% relative bandwidth). Preliminary measurement results are presented. The results are encouraging and perfectly matching simulations. However, the common mode excitation of the vertical feeding lines is significant when scanning towards wide angles.
