Coupler with edge and broadside coupled sections

摘要: Couplers are disclosed that include first and second mutually coupled conductors. The conductors may be regular or irregular in configuration, for example, linear, including rectilinear with one more curves, bends turns, such as forming a ring, coil, spiral other loop. One sections of coupler on different levels separated by dielectric medium, air substrate. Coupled facing each the same spaced-apart surfaces, opposing surfaces common substrate, conductor portions side surface In some examples, plural sections, section being only broadside coupled, another edge-coupled.
