Abstract
The effect of the substrate structure on the radiation properties of microstrip array feed networks is investigated with the space‐domain integral equation approach. Numerical and analytical techniques are employed to produce efficient computer algorithms. Results for space and surface wave losses are presented for corner discontinuities printed on substrate/superstrate, and two‐layer substrate structures. Comparisons are made with the single‐layer case.Keywords
