Brainstorm Optimization in Thinned Linear Antenna Array with Minimum Side Lobe Level
- 162 Downloads
An antenna array (or array antenna) is composed of multiple individual antennas to produce a high directive gain or a specified pattern. Thinning involves reducing total number of active elements, but not to the detriment of system performance. In this paper, a variant of the Brainstorm Optimization (BSO) algorithm is proposed for thinning the linear arrays. The proposed thinning algorithm is employed to minimize the side lobe level and enhance the ratio directivity/side lobe level. The results show good agreement between the desired and calculated radiation patterns with reduction in resource usage in terms of power consumption.
