WebFeb 13, 2024 · Antenna designs comprises: (1) fully filled 8 × 8 planar array (2) optimized thinned planar array and (3) optimized tapered planar array. The main motive is to inactive a few number of elements of a fully filled 8 × 8 array while keeping the gain and return loss undisturbed ensuring the high reduction in sidelobe levels. WebApr 13, 2012 · Thinning involves reducing total number of active elements in an antenna array without causing major degradation in system performance. Dynamic thinning is the process of achieving this under real-time conditions. It is required to find a strategic subset of antenna elements for thinning so as to have its optimum performance.
WebJun 28, 1993 · It is shown how to apply genetic algorithms (GAs) to arrive at an optimally thinned array. Consistent GA results from five array thinning optimizations for a 50-element linear array of isotropic point sources are shown. All of the runs are within 0.8dB of one another.
