Abstract : The paper reviews the present state of knowledge concerning radiation pattern nulls, with a view toward anticipating its occurrence and avoiding or minimizing the effects. In addition, data are presented that describe a new kind of blind spot wherein both the main beam and a grating lobe are simultaneously null, and some new data are included that show an array null can be removed by destroying the symmetry of the array periodic cell.
