Why is 5G called millimeter wave?
These high-frequency bands are often referred to as “mmWave” due to the short wavelengths that can be measured in millimeters. Although the mmWave bands extend all the way up 300 GHz, it is the bands from 24 GHz up to 100 GHz that are expected to be used for 5G.
What is 60 GHz millimeter wave?
At 60 GHz, the wavelength is just 5 mm. This allows the antenna design to be much smaller in size compared to its lower band counterparts. The antenna is built on an FR-4 substrate with a relative permittivity of 4.3. The substrate measures 12.9 mm × 14 mm × 1.6 mm.
Can wavelength be mm?
Some radio waves, another type of electromagnetic radiation, have much longer waves than light, with wavelengths ranging from millimeters to kilometers. Waves of blue light have a shorter wavelength than waves of red light.
What are the 5G mmWave bands?
5G high bands (mmWave, also referred to as FR2) are found in the range of 24GHz to 40GHz. They deliver large quantities of spectrum and capacity over the shortest distances. They also use massive MIMO to expand capacity and extend coverage.
