Abstract
An optimal design for RLSA (radial line slot array) antenna useful for DBS reception is presented. Classical geometries and structures given in the literature are first used. It is found that in some cases thes e are not suitable. So, optimization techniques by using the right obj ective functions have been applied. Two different methods were develop ed and three antennas were designed. Numerical results and comparisons with other similar antennas give the advantages of our design.
