Abstract：The longitudinal slot array of rectangular waveguide's wider side is analyzed and designed according to the equivalent magnetic current. The parameters of the array are obtained with the method of quasi-Newton, and the inner and external coupling coefficients are calculated and taken into account. Because the admittance of single slot is calculate with MOM, and the thickness of waveguide's wall is considered, the convergent rate is enhanced. As an example, an S-waveband slot array of 2×4 elements is designed, and the measured and simulated results are agreed well with each other.
