| Abstract: | To reduce the large-scale computing in cross polarization(XP) evaluation of circularly polarized phased array,a simplified algorithm based on polarization synthesis of array is presented.The parasitic XP array factor of sequentially rotated circularly polarized(SRCP) phased array is derived,and the expression of rotation phase differential matrix(RPDM) is used to explain the principle of parasitic XP of SRCP.The XP property of several kinds of SRCP array composed by linearly or elliptically polarized elements is compared,and the specification of element type and sequential rotation method in millimeter wave communication is listed,which gives the criteria for XP suppression of wide angle scanning phased array. |
