Usually, microwave signals are not used for ionospheric propagation. The reason is
1
Ionospheric layers absorb microwaves tremendously
2
Drastic dispersion takes place for microwave signals in ionosphere
3
Scattering prevents propagation of microwaves through ionosphere
4
Microwaves penetrate through ionosphere layers
