At microwave frequencies, we prefer waveguides to transmission lines for transporting EM energy because of all the following except that (a) Losses in transmission lines are prohibitively large. (b) Waveguides have larger bandwidths and lower signal attenuation. (c) Transmission lines are larger than waveguides. (d) Transmission lines support only TEM mode.
