abstract

  • Mode coupling phenomena on the finite substrate microstip lines are studied. The effect of the finite substrate is related to the general concept of mode coupling initially appeared on stub loaded leaky wave structures. The nonlinear nature of the analysis of open waveguides in general is addressed. Common misunderstandings on the use of HFSS™ regarding such an analysis are dicussed. Preliminary results based on a non-linear eigensolver [1], and their interpretation considering the effect of the finite substrate and the occurrence of a new propagating substrate mode will be presented. Finally, some comments are made on the consequences of this mode and its coupling to the first order leaky mode on the design of patch and leaky wave antennas. © 2011 IEEE.
