Current Distribution on a Grid Type Dipole Antenna Immersed in a Warm Isotropic Plasma


  • Maurice L. Schiff


The current distribution on a grid type dipole antenna immersed in a warm isotropic plasma is formulated from two viewpoints. The first method is a direct source approach; it yields a new integral equation that is an extension of Hallen's equation. The second method is based on a boundary value analysis introduced by Einarsson. The equivalence between the two methods will be shown. A solution to the integral equation valid for thin antennas shows that the current is sinusoidal in form with a propagation constant Ke = (ω2–ωp2)½/C. This result will be compared with the work of Monroe.
