Abstract :
A practical means is described for reducing the mutual coupling and leakage of energy between two flush-mounted slot antennas in a common ground plane by introducing a thin lossy slab on the ground plane between them. Theoretical equations are derived to describe the surface mode, and experimental measurements are reported for the coupling and for the antenna pattern in the azimuthal plane. Results indicate that the method produced 19 db of decoupling without any appreciable effect on the antenna azimuthal beamwidth.
