Radiation characteristics of current elements near a finite-length cylinder
TLDR
In this paper, an analysis using image and geometrical theory of diffraction techniques for calculating the elevation-plane pattern of radial infinitesimal current elements mounted near or on perfectly conducting cylinders of finite length is presented.Abstract:
An analysis using image and geometrical theory of diffraction techniques for calculating the elevation-plane pattern of radial infinitesimal current elements mounted near or on perfectly conducting cylinders of finite length is presented. The radiation problem is resolved into two components, the dipole and the edge contributions. The computed patterns are compared with experimental results since boundary-value solutions are not available. Good agreement between theory and experiment is obtained.read more

Pattern distortion due to edge diffractions
TL;DR: The method of combining wedge diffraction solutions for the analysis of an axial TEM-mode slot is extended here for an arbitrary aperture antenna in a finite size ground plane as mentioned in this paper, where the boundary value solution considers the pattern component when the aperture is in an infinite ground plane, and the diffraction solution (secondary pattern) considers the contribution to the pattern from the edges of the finite ground plane.

Analysis of an array of line sources above a finite ground plane
TL;DR: In this paper, a simplified analysis of the radiation mechanism of an array of line sources above a finite ground plane is presented, which is restricted to two line sources since data are available for comparison, and results on the variation of the maximum field intensity, the angle of maximum field intensities, and the field intensity at the axis of the counterpoise as functions of the ground plane are presented.

Radiation From Conical Surfaces Used for High‐Speed Spacecraft
TL;DR: In this article, the analysis for the radiation pattern of an infinitesimal dipole mounted on the tip of a perfectly conducting, finite length cone is presented, which is constructed from the superposition of a wave radiated directly from the linear element (in the presence of an infinite cone) and a wave diffracted from the edge of the cone.

Diffraction by an Aperture
TL;DR: In this paper, the geometrical theory of diffraction was introduced to account for diffraction by introducing new rays called diffracted rays, which are produced when incident rays hit the aperture edge.

The Patterns of Antennas Located near Cylinders of Elliptical Cross Section
TL;DR: In this paper, small dipole and loop antennas mounted on or near a perfectly conducting cylinder of elliptical cross section are calculated by determining the open-circuit terminal voltages of the antennas when receiving plane waves.
