Antennas are the main element of aerial communications. They are the transition between a transmission line (normally a coaxial cable)

and the free space, in others words, antennas convert voltages and currents of a transmission line into electromagnetic waves as efficiently as possible.

To characterize an antenna it is necessary to understand the basics of antennas and the most important parameters of antennas measurement.

The Computer Controlled Antenna Trainer “EANC” has been designed for full-automatic control of the antenna measurement through the computer PC, which allows students familiarize with automatic antenna analysis.

The “EANC” allows to learn how to perform the most common antenna measurements (radiation pattern, SWR, etc.). It also allows

students to understand when it is necessary to add matching components to reach the correct matching between the antenna, the transmission line and the generator in order to improve the performance of the system.

The trainer is provided with a set of practical exercises, through which the student will understand how to work with the different elements ofwwww

the unit in order to obtain a complete knowledge of the concepts behind antennas.
