Abstract
The electromagnetic spectrum in Table 1 identifies the microwave domain roughly between 300 MHz and 300 GHz. This definition is somewhat arbitrary but has been followed for descriptive purposes and, to a large extent, for commercial purposes. At the lower end of the band, microwaves overlaps the UHF band and at the higher end, they border the far infrared region. In addition to the general domain, microwaves are often identified with subdomains or bands. These are designated by letters to allow simple identification of equipment and operating frequencies. The standard designations are shown in Table 2 and are known as microwave frequency bands. There is a separate military band designation shown in Table 3 and an IEEE band designation shown in Table 4. The relative location of the microwave domain in the electromagnetic spectrum is shown schematically in Figure 1.
