In this paper, a smart antenna with arbitrary down tilt is proposed for 3G wireless communication. In the third
communication generation, the antenna downtilt is a common method used to adjust the interference conditions espe-
cially in urban scenarios with high base station density. The proposed antenna is able to tilt the antenna pattern in the
desired direction as well as null in the interference directions. In the design procedure, the antenna element is de-
signed and optimized to achieve the desired properties for 3G networks. Then a proper algorithm is used to minimize
the noise variance in the antenna output. Finally, some simulations are performed to verify the proposed method. In
these simulations, the antennas down tilts are considered as 0, 5 and 10 degrees with arbitrary interference directions.
Moreover, some antenna with different numbers of interferences are designed and simulated. These results verify the
ability and capability of the proposed method.
