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
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 catches passing EM waves and converts them back into electrical signals for a receiver to process. The physical shape and size of an antenna—whether
