The effects of cavities located near the base of a ground plane-mounted coax-driven monopole antenna are investigated. The cavities are either embedded in the tubular antenna itself or in the region below the conducting surface. Coupled integral equa

A method is presented for accurately modeling a monopole or dipole antenna fed by a coaxial line. The base of the monopole is attached to a conducting plane through which the coaxial feed line extends to the feed. The feed structures considered are e

A technique is presented to efficiently solve for the currents on an appendage, e.g., antenna, attached to a planar surface of a conducting body. The appendage may be embedded in a homogeneous, dielectric material. The technique presented alleviates

A technique is described for determining the field in a series of cascaded, axisymmetric cylindrical cavities excited by a /spl phi/-independent source. The constituent cavities are axisymmetric but may have a cross-section that varies with axial dis

Electromagnetic penetration through an aperture into a cavity is considered. The structure of interest is a semielliptical channel flush-mounted under a metal plane and slotted along the interfocal distance of its cross-section. The channel is filled
