How does a radio frequency antenna work?
How does an antenna work? The antenna at the transmitter generates the radio wave. A voltage at the desired frequency is applied to the antenna. The voltage across the antenna elements and the current through them create the electric and magnetic waves, respectively.
What is a radio frequency antenna?
An antenna is a specialized transducer that converts radio-frequency (RF) fields into alternating current (AC) or vice-versa.
What is the theory of antenna?
The fundamentals of antenna theory requires that the antenna be "impedance matched" to the transmission line or the antenna will not radiate. The concept of VSWR is introduced as a measure of how well matched an antenna is. Bandwidth. The bandwidth of an antenna is the frequency range over which the antenna radiates.
