Abstract
A method for optimizing antenna orientation in a cellular radio telephone system with respect to a predetermined criterion of signal level includes the steps of orienting the antenna in a selected direction, sensing a selected received signal in a predetermined frequency range, mixing the selected received signal with the control signal so as to generate a corresponding intermediate frequency signal in an intermediate frequency transmission path, measuring a selected parameter of the intermediate frequency signal and then altering the orientation of the antenna while subsequently repeating the required steps. The preferred antenna orientation can be determined by examining the results of the various measurements and selecting an antenna orientation which maximizes the signal level of the desired received signal.
