DEVELOPMENTAL PROGRAM FOR THE FABRICATION AND TESTING OF LIGHTWEIGHT WAVEGUIDE, TASK A AND TASK B.
Abstract
This report covers the necessary studies required to fabricate various models to establish sufficient design data for the fabrication of 96 in lightweight serpentine waveguide structures. The electrical length is determined of each serpentine element which will result in an antenna capable of being scanned 0 to 60 degrees from broadside when the input frequency is scanned from 2850 to 3150 mc/sec. Necessary matching structures and compensations are included in the structure to insure that the input VSWR of a 96 in serpentine structure does not exceed 1.5 to 1 over the frequency range. Consideration is given to the power taper in the transmission line and radiation taper along the aperture to provide for an optimum radiation pattern. The serpentine is electrically evaluated to determine the input VSWR and the power output at each coupler when the unit is terminated in a matched load.
