A sequential rotated feeding circuit for sequential rotated feeding of a signal with a wavelength λg is provided. The sequential rotated feeding circuit comprises a feed transformer, a resistance transforming unit, a first antenna transformer, a second antenna transformer, a third antenna transformer and a fourth antenna transformer. The feed transformer has a feed line width resistance Zin. The resistance transforming unit is connected to the feed transformer, the first antenna transformer, the second antenna transformer, the third antenna transformer and the fourth antenna transformer. The resistance transforming unit has a transforming line width resistance Zl. The first antenna transformer, the second antenna transformer, the third antenna transformer and the fourth antenna transformer have an antenna line width resistance Za, and the feed line width resistance Zin, the transforming line width resistance Zl, and the antenna line width resistance Za satisfy the following formula:
Z l=√{square root over (Z a Z in)}.
