Objective To study the optimization technique and mutual coupling compensation technique of ultra-low side-lobe phased array antenna.METHODS A direct optimization and correction method of mutual coupling between antenna elements is proposed.The method uses the constrained nonlinear optimization method to control the ultra-low sidelobe phased array Antenna integrated design, the mutual coupling between the cells directly into the optimization calculation, the antenna array can be integrated optimization and mutual coupling correction completed. Results The antenna array is not scanned and a certain scanning angle, the application of mutual coupling And the optimization results of the direct optimization and correction method are conclusive.Conclusion This method only adjusts the amplitude of excitation to make the antenna array reach ultra-low sidelobe and realize the mutual coupling compensation, which is benefit to the project implementation.
