Antennas And Propagation -

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 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

It catches passing EM waves and converts them back into electrical signals for a receiver to process. It takes an oscillating electrical current from a
