Abstract :
The authors describe a simple method for adjusting the elevations of the antenna elements to suppress interferences coming from certain directions. The effect of changing the elevation of the antenna array elements is to add additional phase to the antenna pattern according to the locations of the nulls with respect to the broadside direction. As an illustration, a linear array with N=20 elements and d=/spl lambda//2 is considered.<>
