Q1:

A (75 - j 50) Ω load is connected to a coaxial line of Z0 = 75 Ω at 10 GHz. The best method of matching consists of using

A a capacitance at some specific distance from load

B a short circuited stub at some specific distance from load

C an inductance at load

D a short circuited stub at load

ANS:D - a short circuited stub at load

A short-circuited stub placed at a suitable distance from load provides best matching.
