Abstract :
A numerical investigation on mutual coupling between two neighboring DRAs suitable for AIA array applications has been presented. The proposed geometries show that the harmonic tuning governing the mismatch of the radiator at higher harmonics, which is vital for a correct PA loading, remains substantially unchanged.
