Microwave propagation pdf

Microwave transmission refers to the technology of transmitting information or energy by the use ofelectromagnetic waves whose wavelengths are conveniently measured in small numbers of centimetre ; these are called microwaves. Microwave communication.

A microwave link is a communications system that uses a beam of radio waves in the microwave frequency range to transmit video, audio, or data between two locations , which can be from just a few feet or meters to several miles or kilometers apart.

Microwaves are widely used for point-to-point communications because their small wavelength allows conveniently-sized antennas to direct them in narrow beams, which can be pointed directly at the receiving antenna .

There are two main types of microwave communication systems. First one is terrestrial system. It relies on transmission through directional parabolic antennas. Signal can only travel to receiver in the line of sight.
