Microwave

These frequencies fall within the microwave band, so radio waves with these frequencies are called microwaves.
In all cases, microwaves include the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum.

Parabolic antenna

The small wavelength of microwaves allows them to be directed in narrow beams by aperture antennas such as parabolic dishes and horn antennas, so they are used for point-to-point communication and data links and for radar.
In order to achieve narrow beamwidths, the parabolic reflector must be much larger than the wavelength of the radio waves used, so parabolic antennas are used in the high frequency part of the radio spectrum, at UHF and microwave (SHF) frequencies, at which the wavelengths are small enough that conveniently-sized reflectors can be used.

Frequencies in the SHF range are often referred to by their IEEE radar band designations: S, C, X, K u, K, or K a band, or by similar NATO or EU designations.
Thus it crosses the conventional boundary between the UHF and SHF bands at 3.0 GHz.

Tropospheric scatter

This is used in troposcatter communications systems, operating at a few GHz, to communicate beyond the horizon.
This method of propagation uses the tropospheric scatter phenomenon, where radio waves at UHF and SHF frequencies are randomly scattered as they pass through the upper layers of the troposphere.

Communications satellite

This frequency range is used for most radar transmitters, wireless LANs, satellite communication, microwave radio relay links, and numerous short range terrestrial data links.
Typically military satellites operate in the UHF, SHF (also known as X-band) or EHF (also known as K a band) frequency bands.

Extremely high frequency

On the other hand, they are the highest frequencies which can be used for long distance terrestrial communication; higher frequencies in the EHF (millimeter wave) band are highly absorbed by the atmosphere, limiting practical propagation distances to one kilometer.
It lies between the super high frequency band, and the far infrared band, the lower part of which is also referred to as the terahertz gap.

Waveguide (radio frequency)

Therefore, to transport microwaves between the transmitter or receiver and the antenna with low losses, a special type of metal pipe called waveguide must be used.
In practice, waveguides act as the equivalent of cables for super high frequency (SHF) systems.

Transmission line

transmission linestransmissiontransmission-line
At microwave frequencies, the types of cable (transmission line) used to conduct lower frequency radio waves, such as coaxial cable, have high power losses.
They are a convenient practical format that fills the gap between lumped components (used at HF/VHF) and resonant cavities (used at UHF/SHF).
