Antennas Radio/wireless phone receiver antennas. Antenna operation: The pulsating magnetic fields produced by a radio frequency (RF) transmitter move across the receiver antenna and ground plane of your car's radio, wireless phone, etc. inducing current into them. Think of the antenna as a piece of wire that has small amounts of AC current (low AC mV) induced in it by the pulsating magnetic fields. The AC currents are fed from the antenna to the receiver where they are interpreted, tuned to the desired frequency, amplified, and then sent to the speaker(s). Radio amplifiers vary in the level of power amplification and the quality of sound amplification. Inexpensive amplifiers may have high power, but they also may cause high levels of sound distortion. Today's automobiles use a variety of antenna types and configurations. Radio (AM-FM) Antennas - AM/FM radio antennas are available in various sizes, placement, and configuration. The antenna shown below is part of the rear window glass; a traditional antenna mast is also shown.
