Concepts and models for advanced designs
In this chapter we will discuss a number of concepts and models used in advanced design and optimisation of slot arrays. Models for coupling slots will be presented followed by a discussion of the edge wall slot and the compound radiating slot. Iris-excited longitudinal slot arrays, slot arrays in ridge waveguides and slot arrays covered by a dielectric layer will also be discussed. Higher-order mode coupling between adjacent coupling slots and that between a coupling slot and radiating slots in its immediate vicinity will be presented. A method of incorporating the finite ground plane effects in the design and analysis will be described. The MoM solution to the coupled integral equations for the apertures of all slots in a planar array will be discussed. Some examples employing the moment method solutions of slot arrays for improved designs will be presented.
