Optimization of switched-beam arrays for communication systems
This paper presents the application of optimization methods for the synthesis
of a linear array for communication systems. By means of suitably beam
switching, the array should provide coverage of a given angular area in azimuth
and should allow controlling the sidelobe level simultaneously. For this
purpose, two optimization methods have been used to calculate the excitation
coefficient for each desired beam. The synthesis technique is demonstrated for
arrays composed of isotropic and microstrip elements. By comparing the results
obtained for both arrays, the need of consideration of the array element
pattern during the synthesis process is demonstrated
