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 ...

We present a two-turns loop antenna with a magnetic core to transfer power wirelessly to a miniature 2 × 2 × 2-mm3 cubic loop antenna in a cortical implant. Compared to a same-sized single-turn loop ...
