Abstract : This is a report on an experimental program with the following objectives: (1) To develop a suitable antenna test range; (2) To determine how closely certain antenna array patterns can be realized and maintained with normal handling of array elements and under normal environmental conditions; (3) To study experimentally the problem of mutual coupling between array elements; and (4) To obtain preliminary experimental verification of side lobe reduction techniques for both equally and unequally spaced arrays. The antenna test range is described, and sample results are presented of measurements of the field intensity at the site of the test antenna. It is concluded that the test range is suitable for use in making antenna pattern measurements. A large amount of experimental data is presented, and the results are considered to be generally good. The patterns of the test antennas are in good general agreement with expected results, and the adverse effects of mutual coupling on the experimental patterns are discussed. Finally, the validity of various side lobe-reduction techniques is demonstrated, which paves the way for more advanced experimental studies of methods of array synthesis and side lobe reduction.
