What is the Microwave Frequency Range?

The microwave frequency range generally spans frequencies from 300 MHz to 300 GHz. Within this range, microwaves can be classified into different bands, such as:

• UHF (Ultra High Frequency): 300 MHz to 3 GHz
• SHF (Super High Frequency): 3 GHz to 30 GHz
• EHF (Extremely High Frequency): 30 GHz to 300 GHz

Each of these bands has distinct properties and applications. For example, UHF is commonly used in television broadcasting and mobile communications, while SHF is essential for radar and satellite communications. EHF is primarily used in advanced research applications and high-frequency data transmission.

How Do Microwaves Work?

Microwaves operate based on the principles of electromagnetic radiation. When a microwave signal is transmitted, it travels through space at the speed of light and interacts with materials it encounters. The interaction between microwaves and matter results in various effects, including heating and reflection.

In microwave ovens, for instance, microwaves penetrate food and excite water molecules, causing them to vibrate and generate heat. This process cooks the food evenly and efficiently. Similarly, in radar systems, microwaves are used to detect objects by bouncing signals off them and analyzing the reflected waves.
