The paper presents a method to mitigate the effect of multipath propagation using an adaptive array antenna. It is shown that, by controlling the number of active elements and their spacing, the array's capability to eliminate scattered signals can be enhanced in the presence of pointing errors. We consider a non-uniform inter-element spacing of the array. In practice, this can be achieved by switching some elements on or off electronically, and/or by mechanical displacement of the elements.
