Abstract
Apparatus for improving the performance and allowing increased directionality of reflecting-type antenna systems by varying the geometry of the reflecting surface. A reflecting surface is composed of an array of actuated pins which are capable of extending or retracting to alter the overall pattern. An actuator controlling unit has the address of each actuator and is able to extend or retract the pins to the desired degree. The specific pattern which the actuator control unit realizes is determined by the iterative position calculator which utilizes directional inputs from the user and/or inputs from a system which determines the effectiveness of previous pin movements. The apparatus attempts to maximize the received signal by assessing amplitude changes over time and utilizing that information to direct alteration in the reflecting surface for optimal performance.
