The one below is the only micro wave network element that is a TEM line:

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

Circular wave guide

Surface wave guide

Co-axial cable

Rectangular wave guide

Correct Answer : Option (C) : Co-axial cable

Explanation : Coaxial cables support TEM mode of propagation in them and rectangular waveguide, circular wave guide, surface waveguides do not support TEM mode of propagation in them.
