Performances of an adaptive array antenna system for land mobile communications have been investigated through computer simulation and experiments. The adaptive array antenna system can automatically form nulls in the direction of undesired wave on receiving directional pattern. First, it is verified by computer simulation that only desired wave is received without interference by the system controlled on the basis of CMA, when the desired and undesired waves arrive at the receiving point together. Next, it is experimentally indicated that the undesired wave is suppressible by approximately 20 dB, even if the antenna element of the system has not an omni-directional pattern. From these studies, it is confirmed that the adaptive array antenna system is very useful for high quality land mobile communications
