Electronics and Communication Engineering (ECE) : Microwave Communication - Quiz(MCQ)

shorted at both the ends

open at both the ends

matched at both the ends

None of the above

Correct Answer : Option (A) : shorted at both the ends

Explanation : A cylindrical cavity resonator is formed by shorting both the ends of the cylindrical cavity because open ends may result in radiation losses in the cavity.
