This paper proposes a novel approach for the spatial microwave power combining. Anisotropic metamatierials are employed to trim the combined electrical flelds and form a single beam radiation pattern. The radiation characteristics of a binary horn antennas array are investigated both numerically and experimentally at 12GHz. The results show that much higher combining e-ciency can be achieved. Given a designed combining e-ciency, the strict relative position requirements in each transmission unit are reduced in this scheme.
