These electromagnetic fields move at the speed of light (about 300 million meters per second or about 186,400 miles per second) through free space.Īccording to Maxwells well-known equations, they However, a brief review of the essentials can help allay any design worries.īoth oscillate at a specific frequency, and they travel together in a direction perpendicular to both fields ( Fig. They may look complex and enigmatic to most engineers, especially EEs working with wireless applications for the first timenot to mention that they come in a seemingly infinite variety of sizes and shapes. Theyre the transducers that convert the voltage from a transmitter into a radio signal.Īnd they pick radio signals out of the air and convert them into a voltage for recovery in a receiver.
