HIGH-FREQUENCY ANTENNA TECHNIQUES

Abstract

Two methods of making efficient, low-height, high-frequency antennas are to be evaluated: (1) using a skeleton slot to obtain a low-height, vertically polarized, wire-slot array over a ground plane; (2) using a microwave troughwaveguide antenna. The first method was investigated during the report period. Three-dimensional patterns of single and double wire-slot antennas were measured in 2 polarizations and they agree with theoretical predictions. Measurements indicate that acceptable impedance levels can be obtained; the gain measurements must be further refined for reliability. Theoretical analyses were made of antenna patterns, polarizations, impedance, and gain. (Author)
