Abstract

"An anechoic chamber for use in the B-12 KHz range was designed and built for the purpose of obtaining the far field patterns of antennas and radiation systems. This chamber was evaluated and compared with various types of anechoic chambers from the standpoint of their "room performance."

The anechoic chamber is essentially a room lined with absorbing material, effective at microwave frequencies. The purpose of the absorbing material within the room is to present the reflection of the energy incident upon the walls of the room.

Measurements of the far field radiation pattern of an aperture in a ground plane, that was unsymmetrically fed by means of a dielectric loaded waveguide, were then obtained in the anechoic chamber. The amplitude and phase distribution across the aperture were also measured. These measured quantities were used to calculate the far field patterns which were then compared to the experimentally measured far field patterns. These patterns were obtained and compared for materials having dielectric constants of 1.7,3, and 6."--Abstract, page ii.
