Large Spacing Array with Offset Phase Center Elements for Highly Integrated Applications
文献摘要：
A scanning and uniform array architecture with large spacing,low complexity and high scalabil-ity is presented for high integration massive array ap-plications.It is constructed by offset phase center el-ements arranged in a uniform and regular way,but its spacing can be larger than that of traditional arrays.An ideal model of the offset phase center element is established and its far-field distribution is derived.To suppress grating lobes,the phase center of any element is designed to be movable without changing its phys-ical position.Using genetic algorithm(GA),a new constraint condition limiting the number of phase cen-ter changes is proposed to solve the objective function of the minimum values of grating lobes(GLs)and side lobes(SLs).It is shown that the optimal results can be achieved by two changes of phase centers.A multi-mode circular patch is developed and designed,and characteristics of the offset phase center are analyzed and verified.A prototype array of 12×12 offset phase center elements is implemented based on multi-mode circular patches.Full wave simulation results of radi-ation patterns show that the level of grating lobes is suppressed at least 7dB with 1.12λ spacing,while the scanning angle is 20°.
