Low profile multibeam dual polarization antenna array with compensated mutual coupling

This paper presents the design of a low profile wideband multibeam integrated dual polarization antenna array for C-band applications. Two three beam Butler beam-forming network (BFN) are implemented in a single layer and integrated with wideband aperture-coupled staked patch elements. By utilizing certain mutual coupling compensation techniques, the array performances, especially the return loss, have been improved. Finally some experiment results are given.
