In this letter, the mutual coupling reduction in airborne co-sited blade antennas is addressed.

Abstract
In this letter, the mutual coupling reduction in airborne co-sited blade antennas is addressed. To suppress the interference between nearby radiators over a wideband, an innovative coplanar printed isolating device is designed by exploiting an extension of the soft surface concept. As a proof of the effectiveness of the proposed approach, a system working in the aircraft L-band is designed that yields a high isolation (with mutual scattering coefficient S12 ≤ −30.8 dB) over a fractional bandwidth of 23.4% without significantly impacting the radiation performance.| File | Dimensione | Formato | |
