Order to make the antenna radiation beam to form a given pattern, using the combination of DFP and BFGS formula variable metric algorithm to optimize the amplitude and phase distribution of each cell of the array antenna feed, calculated through C++ language programming to achieve, which makes optimization array antenna main beam shape is consistent with the pre-to the beam shape to meet the design requirements. Global optimization is a feature of this article, it makes up for the shortcomings of the accuracy of the local optimization results depend on the initial value, and thus can be guaranteed through the optimization of the antenna main beam to coincide with the main lobe of a given beam, sidelobes also been effectively controlled . The method has fast convergence of computing and small volume, is a solution to the array antenna beamforming. Platform: |

Description: Codebook is a known matrix, had been create and setup when initial design a system. Each column in codebook specifies a beamforming weight vector, or in other words, specifies a combination for the phase shifters and amplitude controllers to create a respect radiation pattern. All columns should span the entire space around the beamformer (the device that steers the beam), 360 degree with 1-D array antenna and sphere space with 2-D array. This requirement ensures wherever the beamformee (the target device of the steered beam) locates, there is a weight vector steers the beam to it and keep the channel in good condition. To reduce the complexity and electrical elements, in this paper we consider only the phase in 1-D array antenna by controlling the phase shifters, without examining the amplitude of the signal.

Description: An array factor is a mathematical factor in the directivity equation of an array antenna. It is the factor by which the directivity function of an individual antenna must be multiplied to get the directivity of the entire array.[1][2]
An array antenna is a set of multiple identical antennas which work together as a single antenna. The individual antenna elements are connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase relationship. The radio waves the individual antennas combine and superpose, enhancing radiation in certain directions while suppressing radiation in other directions. The purpose of using multiple antennas in this way is to produce a radiation pattern that could not be achieved by a single antenna. Usually the goal is higher gain (directivity), more of the power radiated in a specific direction.-An array factor is a mathematical factor in the directivity equation of an array antenna.
