This paper describes the characteristics of a microstrip phased array antenna for mobile-satellite communications using the INMARSAT-M system. Attention is paid primarily to the phase control and measurement of the antenna with particular emphasis on testing techniques. Using the Near Field/Far Field technique it is possible to examine the antenna in the Near Field, thus permitting a detailed examination of each radiator. In this way it is possbile to observe malfunctioning in the antenna without recourse to interpreting far-field measurements. A simple test procedure is outlined in which faulty elements can be identified.
