Antenna pattern synthesis based on the particle swarm optimal algorithm

Multiplexing Antenna Arrays is the anti-interference key technology of 4G mobile communication. The core is the antenna pattern synthesis. Yet some of the algorithm have the problem of needing lots of data, high computational complexity and slow speed of convergence. In this paper the improved antenna pattern synthesis based on particle swarm optimal algorithm is presented, Then simulator is carried out. Compared with others., it has the small calculation quantity, the easy realization, the good steady, no many parameter demand adjust and stronger application.
