摘要：
An innovative architecture is proposed for tightly coupled dipole arrays partitioned irregularly by domino shaped tiles. A 192-port finite array operating at 8-12GHz has been implemented, where the port spacing is 0.576 wavelength at the highest frequency. In order to achieve large elevation angle scanning, differential evolution (DE) algorithm is used to synthesize active radiation patterns and suppress the port active reflection coefficients simultaneously. Simulation results show that the finite array is able to achieve almost no reduction in gain for scanning to broadside and only less than 2dB for scanning up to 60 degrees as compared to fully populated arrays.
