Abstract: Magnetic-field (H-Field) forming using planar multicoil transmitter antenna is presented. To address angular misalignment in inductive coupling systems, three orthogonal H-field components are formed in near-field zone of the transmitter antenna. This proposed magnetic field forming is performed by analyzing near-field distributions of various combinations of spatially distributed coils. The analytical study evolves into the planar multicoil design achieving three orthogonal components of H-field formed in target receiver area. The proposed antenna is realized in printed circuit board technology, simulated, and measured to validate the claim. The results corroborated with the analytical results and proved potential of the proposed design suitable for inductive coupling based applications like radio frequency identification, wireless charging, near-field communication, and medical implantation.
