| Summary: | An antenna array is a set of a combination of two or more antennas in order to achieve improved
performance over a single antenna. This paper investigates the beam steering technique using the active
element pattern of dipole antenna array. The radiation pattern of the array can be obtain by using the
active element pattern method multiplies with the array factor. The active element pattern is crucial as the
mutual coupling effect is considered, and it will lead to an accurate radiation pattern, especially in
determining direction of arrival (DoA) of a signal. A conventional method such as the pattern multiplication
method ignores the coupling effect which is essential especially for closely spaced antenna arrays. The
comparison between both techniques has been performed for better performance. It is observed that the
active element pattern influenced the radiation pattern of antenna arrays, especially at the side lobe level.
Then, the beam of the 3x3 dipole antenna array has been steered to an angle of 60° using three
techniques; Uniform, Chebyshev and Binomial distribution. All of these are accomplished using CST and
Matlab software |
