In this paper the design equations for an array of circumferential slots on a
cylindrical waveguide are obtained, following the procedure introduced by Elliott
for slots on rectangular waveguides. The minimization of the error function
is achieved for optimization of slot array parameters. The optimization of
slot parameters is not goal of this paper but a numerical example are presented
as illustrations of the proposed synthesis method. The results of array
designs by the method of the least squares are verified by two computer simulation
softwares, namely CST and HFSS.
