Implementation of Ant Colony Optimization (ACO) in Linear Antenna Arrays for SLL Reduction

TRM antenna is the one of the component of the Wireless System Network. It is used in Wireless network to improve the throughout and efficiency of the network. The TRM antenna is used in satellites, SONAR for acquisition of signals. Due to large number of arrays presents, sometimes TRM antenna failure takes place. When a transmitter/receiver module (TRM) error occurs, the beam pattern is distorted. In this case, resynthesizing the optimal beam pattern with all functioning TRMs, without failed TRM, is preferable to TRM repair or replacement. The degradation of the capacity of transmitter/receiver module (TRM) distorts the beam pattern; that is, the side lobe level (SLL) increases. Lot of research has been done on the optimization of the antennas, but the focus will be on the usage of ACO. Firstly, antenna failure takes place. Then compensation will be done by using ACO and the whole simulation will be shown in MATLAB environment.
