Why are waveguides operated in the microwave range of frequencies?

"Waveguide has a number of advantages over coax, microstrip and stripline. It is completely shielded (excellent isolation between adjacent signals can be obtained), it can transmit extremely high peak powers and it has very low loss (often almost negligible) at microwave frequencies."

waveguides have cut-off frequencies below which they can't operate. It kind of operates like a high pass filter.
