Abstract :
A method for calculating current distributions on a phased array antenna is presented. The method produces steerable major lobes for transmission purposes and multiple independently steerable nulls for rejection of unwanted signals during transmission. The method allows fine tuning of the nulls based upon a set of linear equations and is ideally suited to the implementation of vertical phased array antenna systems operating in the HF frequency spectrum. Several examples are presented.
