摘要：
A method and apparatus are provided for operating a phased-array antenna (14) on a satellite-based communications node (10) in more than one mode by controlling the number of beam-forming elements and by applying appropriate phase-control and/or amplitude-control coefficients to the selected elements. The antenna can be operated as a diffused-beam antenna at a relatively low data rate, enabling the satellite-communications node (10) to communicate with a first terrestrial communications node (22). The antenna can also be operated to generate multiple focused-beam antenna patterns each communicating at a relatively high data rate, enabling the satellite-communications node (10) to communicate with a different terrestrial communications node (20) by changing the amplitude and/or the phase coefficients as well as the number of beam-forming elements.
