This letter suggests an efficient dipole antenna alignment for the collinear dipoles and parallel nonstaggered dipoles in near‐field region, where a material shell or a metal plate is located between two dipole antennas. For an infinitesimal electric dipole in the material shell, a strong electric field direction of outer material and the distance to maintain the field dominantly regardless of the material properties have been calculated. Transmission coefficients of the two dipoles for the metal plate are simulated and measured at 900 MHz. Finally, it is proposed that the transmission performance of the collinear dipole alignment for both the material shell and metal environments is better than that of the parallel nonstaggered dipole alignment. © 2015 Wiley Periodicals, Inc.
