An antenna array (e.g., microstrip patch antenna) operates in a manner that exploits the particular susceptibility of the mutual coupling effects between radiating elements in the array. Various differential-mode excitation schemes are provided for determining optimal differential-mode voltages or optimal differential-mode currents that are applied to the radiating elements (e.g., microstrip patches) to thereby achieve certain desirable radiation characteristics including, for example, aiming a radiated beam in a prescribed direction, steering the beam, shaping the radiated beam, and/or optimizing the gain of the antenna in a specified direction.
