In this letter, a novel kind of coupling mechanism for orientation insensitive and superior transmission performance is proposed. The transmitting coil is comprised of a cubic-type magnetic dipole, ...

Abstract: A decoupling method for magnetic dipole antenna array based on mu-near-zero (MNZ) metamaterials is proposed in this paper. A small loop antenna with a circumference of 0.085λ 0 is used as an ...
