Smart Antenna Design with Arbitrary Tilit for Wireless Communication

Document Type : Original Article

Abstract

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.
