Abstract :
The results of numerical simulation are presented for an array of two-mode slot-coupled parallel plate waveguides excited by TEM modes through dominant mode waveguides and two-step junctions. It is shown that flat-topped element patterns formed by this simple structure are no worse than those of a known array with power dividers and directional couplers.
