Abstract
The use of circular arrays for smart adaptive antenna for wireless communications was discussed. The adaptive antenna reduces the interference coming from other directions by forming ideally nulls in the radiation pattern towards the interferers. The basic symmetry of uniform circular array (URA) offers a great ability to compensate for the effects of mutual coupling by breaking down the array excitation into a series of symmetrical spatial components. The algorithms applicable to circular arrays that form the adaptive beamforming techniques includes least mean square (LMS) algorithm, recursive least square (RLS) algorithm and the conjugate gradient algorithm.
