Abstract:
An antenna is a device (usually metallic) for sending or receiving electromagnetic waves. The antenna is an important part of radio equipment. The antenna has to be tuned to the right frequency or the radio waves can neither be emitted nor captured efficiently. In transmission, a radio transmitter applies a radio frequency to the terminals of the antenna and then the antenna radiates the energy from the antenna as electromagnetic waves. In reception, an antenna intercepts some of the power of an electromagnetic wave to produce a radio frequency at its terminals that is applied to a receiver in order to be amplified and demodulated. In some cases the same antenna can be used for both transmitting and receiving. There are several different kinds of antennas available at Future Electronics. We stock many of the most common types categorized by several parameters including operating frequency, power handling, gain, operating temperature range and type. These types include rubber ducky, embedded, conformal and weatherized.
