The physical shape and size of an antenna—whether it's a simple monopole (like on a car), a parabolic dish (satellite TV), or a microstrip patch (inside your phone)—determine its gain (strength) and radiation pattern (direction). 2. Propagation: The Journey
It catches passing EM waves and converts them back into electrical signals for a receiver to process. antennas and propagation
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). The physical shape and size of an antenna—whether
It takes an oscillating electrical current from a transmitter and turns it into an electromagnetic (EM) wave that radiates outward. The field of is the backbone of all
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
