SELF AND MUTUAL ADMITTANCE OF RECTANGULAR-SLOT ANTENNAS IN THE PRESENCE OF AN INHOMOGENEOUS PLASMA LAYER.

Abstract

The self and mutual admittances for a pair of identical rectangular-slot antennas in an echelon configuration in the presence of an inhomogeneous plasma layer are derived using stationary expressions. Computations using the dominant TE sub 01 mode of the waveguide as a trial field are compared with experiments using a wide variety of configurations of space cloth to validate the computational techniques. These self and mutual admittances are then used to calculate the VSWR and isolation for a pair of rectangular slots in the presence of a typical boundary layer plasma on a sharp, slender conical body. The number of steps needed to adequately approximate the profile is determined together with the range of validity of various thin and thick sheath approximations. (Author)
