Reconfigurable 3D beam steering for intelligent antenna system

A reconfigurable three-dimensional beam steering antenna for intelligent antenna system is presented. The proposed antenna is composed of a triangle loop antenna and two bended dipole antennas with four switches to steer the antenna beam patterns in both of the x–y and x–z planes. The operation frequency of the antenna is 2.5 GHz. The peak gain values are 1.04–2.06 dBi. The overall half-power beam width (HPBW) is about 160° in both of the x–y and x–z planes. © 2011 Wiley Periodicals, Inc.
