A lossy open stub having a length of $1/32$ wavelength, is approximately equivalent to
- A. A small capacitor in shunt with a small resistor
- B. A small capacitor in shunt with a large resistor
- C. A small inductor in shunt with a small resistor
- D. A large inductor in shunt with a large resistor
Answer: B. A small capacitor in shunt with a large resistor
Explanation: $\beta l = \frac{2\pi}{\lambda} \times \frac{\lambda}{32} = \frac{\pi}{16}$. For an open stub, length less than $\lambda/4$ behaves capacitively. A lossy open stub introduces a parallel resistor which is large.
