An improved design procedure for small arrays of shunt slots
Abstract
An earlier design procedure, valid for arrays of longitudinal slots fed by air-filled rectangular waveguide, is generalized to apply to the increasingly used practical case that the waveguide is dielectric-filled. This requires abandonment of the model of an equivalent array of loaded dipoles, which results in a surprisingly simpler and more direct derivation of the design equations. The new generalized procedure retains an important feature of the earlier approach in that it includes the effect of external mutual coupling.
