bandwidth ofa quater wave microstrip

could any one tell me whats the bandwidth of a quater wave and half wave transmission line. how the bandwidth of microstrip lines are great than the lumped components

The bandwidth of microstrip transmission lines in general is related to their Q factor and dispersion (higher the dispersion lower the Q), both affected by the dielectric material. See the image for Qfactor of various transmission lines.

Lumped components (especially SMD inductors) have very low Q factors (generally range between 10 to 100).
