“…For example, in the analysis, we used the distribution of the electric field in the gap in the form of a constant step, which was applied to approximate the excitation electric field in the gap of a loop antenna [22].…”

We reduce the problem of the current distribution over the surface of a microstrip dipole in the form of a thin, perfectly conducting strip on a dielectric substrate, which is metalized on one side, to a singular integral equation with the Cauchy kernel. The complex-valued current distributions on the dipole surface are presented along with the dependences of the input impedance on the dipole-arm length normalized to the wavelength for different values of the dielectric permittivity of the substrate.

“…Much previous work on the current distribution and input impedance of a loop antenna immersed in a magnetoplasma refers to the case where the plasma parameters are independent of the spatial coordinates (see, e.g., [1,2] and references therein). In the past decade, a substantial degree of interest has been shown in the characteristics of loop antennas in inhomogeneous plasma media [3].…”

The problem of the current distribution and input impedance of a circular loop antenna in the form of an infinitesimally thin, perfectly conducting narrow strip coiled into a ring is considered. The antenna is located on the surface of an axially magnetized plasma column and is excited by a time-harmonic external voltage. The problem is reduced to a system of integral equations for the current. On the basis of solutions of these equations, the kernels of which have logarithmic and Cauchy singularities, it is shown that the presence of a plasma column can significantly influence the current distribution and input impedance of the antenna compared with the case of its location in free space or a homogeneous magnetoplasma the parameters of which coincide with those inside the column.

“…In most papers on the subject, dipole and loop antennas in a homogeneous plasma medium are considered [1][2][3][4][5][6][7][8][9][10]. By resonant magnetoplasma, we mean a cold, collisionless magnetized plasma in which the refractive index of one of the characteristic waves tends to infinity when an angle between the wave normal direction and an external dc magnetic field approaches a certain value determined by the plasma parameters.…”

“…By resonant magnetoplasma, we mean a cold, collisionless magnetized plasma in which the refractive index of one of the characteristic waves tends to infinity when an angle between the wave normal direction and an external dc magnetic field approaches a certain value determined by the plasma parameters. In this case, the classical thin-antenna theory cannot be employed readily since no matter how small the cross section of the antenna wire might be physically, it is always possible to find some wave normal direction for which one wavelength in the plasma medium will become less than the wire cross-sectional extent and the antenna conductor will appear to be "thick" [2,3,9,10].…”

Abstract-We study the electrodynamic characteristics of a strip loop antenna located on the surface of a circular column filled with a resonant magnetoplasma and surrounded by a homogeneous isotropic background medium. The antenna current is excited by a time-harmonic voltage creating an electric field with the azimuthal component in a narrow gap on the strip surface. It is shown that the current distribution and input impedance of such an antenna are strongly influenced by the presence of an infinite number of propagating quasielectrostatic modes that are guided by a column containing a resonant magnetoplasma.
