Near-field antennas design with crossed-field elements to enhance the EM field strengths in the near zone

摘要

This paper presents the concept of antenna design to radiate strong reactive fields in the vicinity of antenna. This antenna will compose the electric and magnetic fields in a manner similar their relationships in the far zone, and retains good radiation efficiency. Theoretic examination is first performed. Both numerical and experiment results will be presented in comparison with standard dipole and monopole antennas to justify the validity.
