What is formed by the combination of the UHF, SHF, and EHF bands?

The combination of the UHF (Ultra High Frequency), SHF (Super High Frequency), and EHF (Extremely High Frequency) bands forms the microwave region of the frequency spectrum. These frequency bands, generally considered to range from about 300 MHz (UHF) up to 300 GHz (EHF), are categorized as microwaves due to their properties and applications.

Microwaves are notably used in various technologies such as radar systems, satellite communications, and microwave ovens. The ability of these frequencies to penetrate through the atmosphere and their effectiveness in high-data-rate transmissions is crucial for modern telecommunications and broadcasting. Therefore, understanding that UHF, SHF, and EHF encompass the microwave region helps clarify how they are utilized in practical applications across different technologies.
