	%X This paper describes optimal thinning of an Elliptical 
Cylindrical Array (ECA) of uniformly excited isotropic antennas 
which can generate directive beam with minimum relative Side Lobe 
Level (SLL). The Particle Swarm Optimization (PSO) method, which 
represents a new approach for optimization problems in 
electromagnetic, is used in the optimization process. The PSO is used 
to determine the optimal set of ‘ON-OFF’ elements that provides a 
radiation pattern with maximum SLL reduction. Optimization is done 
without prefixing the value of First Null Beam Width (FNBW). The 
variation of SLL with element spacing of thinned array is also 
reported. Simulation results show that the number of array elements 
can be reduced by more than 50% of the total number of elements in 
the array with a simultaneous reduction in SLL to less than -27dB.
