Antenna systems’ exploitation in radar techniques and communication systems are affected by interference and obstruction. Adaptive antenna systems help to increase the efficiency of any communication system by reducing electromagnetic interference and obstruction.A system consisting of an antenna array and a processor is basically an adaptive antenna array. These antennas change their radiation diagram automatically in response to their signal surroundings. To facilitate this need adaptive antenna arrays are normally used.This seminar examines the general physical design of adaptive antennas. The principle behind the arrangement is examined along with the workings and the mathematics involved. This seminar also devotes its attention to the current industrial applications and trends associated with adaptive antenna arrays. The adaptive antenna’s growing influence in the communication industry is especially examined. The system specific architectures and implementation mechanisms are also examined.
