Mutual Coupling and Impedance of a VLF Curtain Array in an Anisotropic Magnetoplasma

Radiation From a Multiple Dipole Antenna With Phased Excitation in a Magnetoplasma

“…where the symbol Q α denotes the regions Q o and Q e of integration over the positive real q values for which the functions p o (q) and p e (q), respectively, are purely real, and P m,α (q) is the power normalization quantity, which is expressed as P m,α (q) = (−1) m N m,α (q)/4. Substituting the expansion coefficients ( 17) into (20), with allowance for the fact that they are independent of s, and denoting the partial contribution of the mth harmonic to P Σ as P m , we get…”

“…The simplicity of realization of antenna systems on the basis of electric dipoles makes them attractive in comparison with other types of antennas. Despite the recent upsurge of interest in the characteristics of electric dipole antennas and their arrays in a magnetoplasma [15], [16], [17], [18], [19], [20], only one theoretical work [21] has been published to date on the radiation characteristics of a phased electric-dipole array capable of exciting twisted waves under ionospheric conditions, as far as we are aware. The analysis in [21] is primarily focused on the input impedance of a turnstile antenna in the form of two orthogonal electric dipoles with quadrature-phased currents in the VLF band.…”
