The antenna noise temperature is a measure that describes the noise power received by the antenna at a given frequency. In standard array theory we generate a one-way antenna pattern because we consider an antenna radiating toward a target (the transmit antenna case) or a target radiating toward an array (the receive antenna case). mitter leaves the information, which is shown in blue, at low frequencies so that it can not be radiated; the radiating antenna only broadcasts high frequencies. By definition, an antenna is a device used to transform an RF signal, traveling on a conductor, into an electromagnetic wave in free space. Lessons will cover the antennas, their characteristics, their specifications and what the specifications mean.
