"WebApr 11, 2024 · The stub is placed in parallel. Think about it, if you have the impedances Z 1 and Z 2 in parallel, in order to find the equivalent impedance you would need to do Z e q = 1 1 Z 1 + 1 Z 2 But a simpler way would be to find what you have in the denominator, which are the admittances. Call Y 1 = 1 Z 1 and Y 2 = 1 Z 2. " - Stub in electronics

Stub in electronics

In microwave and radio-frequency engineering, a stub or resonant stub is a length of transmission line or waveguide that is connected at one end only.
