Study antenna array with this tool. Radiation Diagram of an Antenna Array help you study the effects of the number, distance and phase shift of several coupled antennas on the radiation pattern.
In wave theory, a phased array is a group of antennas in which the relative phases of the respective signals feeding the antennas are varied in such a way that the effective radiation pattern of the array is reinforced in a desired direction and suppressed in undesired directions.
This technology was originally developed by Luis Alvarez during World War II as a rapidly-steerable radar system.
Nowadays antenna arrays are found at almost all mobile radio base stations, and radio and television broadcasting stations. Their advantages result from their ability to achieve increased gain and improved directivity.
It is possible to select or mask targeted reception areas. The necessary transmission power is also reduced due to the corresponding increase in antenna gain.
