Antennas And Propagation -

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

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 antennas and propagation

It takes an oscillating electrical current from a transmitter and turns it into an electromagnetic (EM) wave that radiates outward. It catches passing EM waves and converts them

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
