Multiport circuit models are presented to emulate a new class of periodic anisotropic crystals exhibiting dispersion diagrams with degenerate band edges or stationary inflection points (SIPs). Specifically, a 4-port lumped circuit is introduced to model a partially coupled pair of microstrip lines known to emulate propagation in an anisotropic medium. A 6-port circuit is also presented to model three...
Partially coupled microstrip lines are presented to emulate periodic anisotropic crystals exhibiting dispersion curves with degenerate band edges (DBE) or stationary inflection points (SIPs). The subject dispersion curves are designed via equivalent circuit models and used to produce miniature printed antennas. A 6-port circuit is also presented to model three partially coupled lines. Under specific...
