Antennas And Propagation -

It catches passing EM waves and converts them back into electrical signals for a receiver to process.

The field of is the backbone of all modern wireless technology, bridging the gap between electrical signals in a wire and electromagnetic waves in the air. 1. The Antenna: The "Transducer" At its simplest, an antenna is a converter (or transducer). antennas and propagation

Propagation describes how those radio waves travel through the environment once they leave the antenna. Waves don't always travel in a straight line; they interact with the world in several ways: Antennas & Propagation short course - University of Surrey It catches passing EM waves and converts them
