DECOUPLING OF TWO CLOSELY LOCATED DIPOLES BY A SINGLE PASSIVE SCATTERER FOR ULTRA-HIGH FIELD MRI

DECOUPLING OF TWO CLOSELY LOCATED DIPOLES BY A SINGLE PASSIVE SCATTERER FOR ULTRA-HIGH FIELD MRI

We report decoupling of two closely located resonant dipole antennas dedicated for ultra-high field magnetic resonance imaging (MRI). We show that a scatterer slightly raised over the plane of antennas grants a sufficient decoupling even for antennas separated by very small gap (below 1/30 of the wavelength). We compare the …
