PATTERN HANDBOOK. VOLUME 6: FAR-FIELD PATTERNS OF A LINEAR ANTENNA ADIATING IN THE PRESENCE OF CIRCULAR CYLINDERS

Abstract

The prediction of fields radiated by shipboard antennas is complicated by the presence of parasitically excited superstructure which warps and deteriorates the far-field patterns. This handbook has beem compiled, giving patterns of a thin, linear, vertical antenna radiating in the presence of cylindrical conducting structures of various cross-sectional shape. The model used to approximate this confi7uration is that of an infinite line source, representing the dipole, radiating in the presence of an array of thin, infinite wires parallel to each other and outlining the surface of the offending cylindrical structure. Only offending structures up to 2 wavelengths on a side are considered. It has been found from sample calculations that patterns for objects larger than 2 wavelengths on a side do not differ radically from those for the largest objects presented in this handbook. The computer program used to calculate the patterns in this handbook is an automated version of the SCATRAN program.
